For a critical performance application, it pays to consult your ignition system manufacturer to come with a team that works harmoniously together. *** The Official Superduty Morning Coffee Thread ***, Novel Research: 1975 E- and F-Series Ignition Systs, Do Not Sell or Share My Personal Information. While the coils draw the same power as with points when they are closed, the current power draw time for the electronic switch is increased from 34.29 Watts to 55.88 watts power consumption, just by using the Dyna-S. Now add 3 ohm coils And the Dyna-S. 12.6V / 3 ohms = 4.2 amps. Usually 10 amps or less - the wires to the coil tend to be 14/010 same size as used for indicators etc. so i believe the ohm would be between 2-4. Send this link to your mates to get $50 OFF their first course. How can I tell if a car has a speed density tune? No coupon needed. runs on 6 or 9V) that bypasses the ballast resistor when starting the engine . You can also lose some spark intensity when you run a coil wire to an external oil-filled coil as the voltage has to travel a longer path, creating more resistance. The advance curve on a stock HEI is for the most part not fully advanced until 4,000-4,500 rpm, which is very slow. Browse other questions tagged, Start here for a quick overview of the site, Detailed answers to any questions you might have, Discuss the workings and policies of this site. Some extremely high-output coils may only be used in short-duration drag racing, as compared with others optimized for long-duration oval track or an extended lifetime of street performance. Smallish reed relays with 12V coils are in the 12mA range. Take a look and see what you think. We've had the daylight lighting laws since the mid 70s but I've had the impression that the U.S. still doesn't.I have CB350 twin and Kawi triple that were imported before the law came into effect and I intentionally switch the lights off during the day to ease the load on the alt. The starter cranks a stock flathead engine at 100 rpms. I used a Pico Scope 2202 and a Pico TA018 current clamp to measure current draw from the coil and establish the charge time (dwell) required for maximum spark energy (saturation?). 6 volt coils (and 12v coils that use a resistor) usually have a primary resistance of around 1.2-1.5 ohms. I'm not at the shop so I can't check the resistance. As mentioned, it's not going to exceed ten amps anyway. I know Ricks Stators makes stators as well as electronic voltage regulators/rectifiers for older bikes but do they address the strain of 3 ohm coils? I have created a document to keep me organized and I will attach. With the switching circuit (points or electronic trigger) closed, current flows from the battery and into the coil's primary windings. No in general it draws less. Usually, systems dissipating 120 watts use fans for air cooling, and it is hard to believe that a really tiny momentary spark inside a cylinder would be 120 watts averaged over the rotation of the engine. Privacy Statement - The ignition has sensed either too much current or a short circuit draw from the coil (S), or seen excessive charging system voltage. HEI draw at idle, depending on the coil used, runs about 3.5 to 4.0 amps average at idle speeds, lowers considerably as the engine rpms rise. More heat, more resistance. Always refer to 53 A . The number of amps used by a starter motor can vary significantly between vehicles. So relays must be a common requirement? How many amps does a 12v coil draw? Thanks I figured .83 amps for coils up to 19.8 ohms. Discussion in 'The Hokey Ass Message Board' started by mart3406, Jan 22, 2010. Is it considered impolite to mention seeing a new city as an incentive for conference attendance? Isn't it a bad idea to have 20awg wire protected with a 15a fuse? Great work on everything presented in the learning modules! Anyone here knowing how many watts can a ignition coil draw without putting CDI or Stator in harm's way?

It takes an (ignition) village: In sum, to achieve maximum performance, the coil should be optimized for the type of ignition system employed (inductive or capacitive discharge) and distributor's switching mechanism (points or electronic), expected engine operating rpm range, and duty cycle (street, short-duration racing, or endurance racing). plunger is held in position by the hold-in coil's magnetic force. We have to account for the 80% breaker rule. Send this link to your mates to get $50 OFF their first course. Choose your class below for more information and to register. We got somethin' in this territory called the Missouri boat ride." 731 Fuel Injectors - 4 to 6 amps peak, 1 amp hold See all 6 photos. I mentioned this before, if you take the time to read what I wrote. A 100:1 turns ratio (typical of many coils on the market) means there are 100 secondary turn windings to every one primary turn. i wonder if someone can help me to cover some of the missing pieces. . It may not display this or other websites correctly. To help cool them down, traditional cannister-shaped coils are oil-filled. What kind of tool do I need to change my bottom bracket? Also, the capacitor and points / contacts are only designed for the small current flow and they have to operate at 1/2 * engine rpm (or one per two revolutions for a four stroke). How many amps does a 12v ignition coil draw? Isn't it all so clear now? Actually most HEI systems run well with spiral-core wires. Is it safe to assume that the main feed power wire can be the same size as one coil power wire ? Why is that? 14.5/1.5 = 9.66 amps x .66 = 6.375 amps, well under 8 amps. (usually expressed as milliamps; 1 milliamp = 1/1000 amp). And the iron core is no longer a round tube in the new designs. Hell it ain't even math - it's arithmetic. By logging into your account, you agree to our, I'm in need to know of how many Volts/Amps the DuraSpark_II system. Myth 7: Because this is a high-compression high-horsepower motor, use solid core plug wires. How many amps does it take to run a car? View attachment 8510 jeff. Engineers refer to a coil's time-charge factor as "dwell," which is expressed in crankshaft degrees. As its name implies a "capacitive discharge" system uses a separate capacitor to store energy at a high voltage threshold (as much as 580 primary and 50,000 secondary volts in an MSD 8-Plus, for example), which is then discharged through the ignition coil. When it gets weak it will still glow but usually is di. Do Not Sell or Share My Personal Information. Use an accurate multi-meter with an amprobe to measure the amps with the burner running at rated voltage and actual load conditions. I'm trying to understand how this works and I use the analogy of electrical current like water a lot. However, if resistance is too low, the higher current could damage the distributor's points or electronic trigger. Several factors play into this, including the operating voltage and the state of the starter and wires. You guys managed to get a law repealed? If you measure the resistance of one of the resistors in your resistor box, and then add in the resistance of your injector, you have your R value to work out your peak current. What causes a starter to draw too many amps? What screws can be used with Aluminum windows. Just out of interest what current does an AC Contactor coil take? #2. Smart electronic systems will adjust the dwell time to ensure that enough magnetic field is built up for a good charge. You must log in or register to reply here. If you have a ballast coil (e.g. The OEM fuse will be protecting all four coils, so the 15A rating makes sense there. Even though I haven't had an alternator problem in 36 yrs. Blue is coil current, red is ecu signal voltage, green is coil voltage and brown is coil earth. Terms of Service. Cheers . Myth 6: There is a specific #1 terminal on the distributor cap. ("1K ohm. Unexpected results of `texdef` with command defined in "book.cls". I have a new stator and electronic voltage regulator from Ricks Stators on my 71 cb350 and have had no charging issues at all since I installed it but it still has factory coils and points ign. At 13.0 volts the current draw went to 0.14A. Just how does an ignition coil work to step up a battery's 12 volts (even less with a ballast resistor) to the tens of thousands of volts needed to fire the spark plugs? 16 would probably work but it doesn't hurt to go bigger. It's that easy. Dec 6, 2005. To illustrate, an oil-filled ignition coil might require about 4 amperes of current at 12 volts to produce 20-30 kilovolts (kV), while a modern e-core or coil-on-plug configuration might require about 7 amperes of current at 12 volts to produce 30-60 kV of high-intensity spark. 12 gauge wire for AC cooling unit that has as 30amp startup but runs on less than 10amp pull, Put someone on the same pedestal as another. For the most part there is only minor benefit to a billet distributor housing over a cast housing, at least in terms of better performance. When you click on links to various merchants on this site and make a purchase, this can result in this site earning a commission. However, it is recommended that you connect your vacuum advance hose to direct manifold vacuum because it will provide you with more vacuum advance at idle, which will help to keep your plugs cleaner. With the system operating, it is more of an IMPEDANCE thing than straight resistance, but the current draw will likely be in that 4 Amp neighborhood. Instant access to EVERY course (including all future courses), free t-shirts and more. Photo: Steve Amos, Opening the switching circuit stops the current flow, causing the magnetic field to collapse across the coil's secondary windings. It should be around that to draw enough current to magnetize the core between firings, but not so much that the points fail right away. The circuit is a 220v 20amp motor. Notice I said VOLTAGE. The HEI distributor is still an inductive-discharge ignition, but exchanges points for an electronic device called a module. To measure this properly, you're going to need a 5Watt 0.1Ohm resistor, and an oscilloscope. As a result, there is not enough voltage left, to power the ignition system and fuel injectors. A quick answer is no, a 3 Amp switch will either weld the contacts together or melt them. Join our newsletter for exclusive FREE content including This includes stator, spark plug wires, spark plug cap, and ignition coil. THAT "batch" is common with 10 AMP draw each X 50% Duty Cycle = 20 AMP each side. To say it's a mite confusing is an understatement! JavaScript is disabled. It looks like that 115 Coil will draw around 16 amps with 3 ms dwell time. Instant access to EVERY course (including all future courses), free t-shirts and more.

Always size your wire and it's length to the current demands. The ignition box requires 12v to run, and 12v during starting only for the timing retard function to work. Does Chain Lightning deal damage to its original target first? Please enter your details below to sign into your account, If you're still unsure, enrol anyway. By comparison, a 72-volt system is much more powerful than a 36-volt system. I heard it was small. Knowing that I = V/R, your current is then your measured voltage divided by the resistor value, 0.1Ohm, which is the same as multiplying your measured voltage by 10. This shortens component life. Archive - SMOKSTAK is a Registered Trade Mark in the U.S. Resistance is futile: Coils with even the same turns ratio can still have varying amounts of resistance. 106 TRO YOUR BOAT ON THE WATER Johnson/Evinrude DVA (Peak Reading) Voltage and . Please register or login to enable Dark Mode. A V10 engine with Coil-On-Plug and 20% duty cycle, would require more total current than a single coil would. 100ms/rev x 1000rpm = .001sec/rpm x 1000 rpm = 1 sec of current draw at 4 amps per minute while running at 1000 rpm. On an HEI, if you use the holes in the housing that were originally there for the vacuum advance, to install your vacuum advance eliminator, there is no cause for rotor phasing. See some detail here: If your low-end cam power band begins at 2,500 rpm (or below), then your advance curve will not be matched to your camshafts power-band, which will result in a significant horsepower/torque loss. See where the slope of the current starts to rise -- that is becuase the coil is fully saturated, and extra energy is just going into making heat. Advertising - As this current rise is linear, you can take the average value of it, right in the middle, and call that your constant coil current over the dwell period. The following are the 10 most common, along with some views, which are believed to dispel them. Post. So, let's do the math on 3ms/16 amps. Invariably, a coil intended for use with a CD system has a different turns rate, internal resistance, and rise time compared to a coil used on a traditional inductive system. One amp cl. Dyna states in their installation instructions that the minimum requirement for the Dyna S is 3 Ohms, but their 5 Ohm coils (or for that matter, stock Honda 5 Ohm coils in really good condition) work fine with the "S". Many contactors can actually be pulled in using 12VDC because there is no inductive reactance with DC voltages. Coil still gets pretty toasty after a while. This is the value to consider when sizing the wire. Spark wise there is no difference between the two. The spark plugs then use this burst of high-voltage electricity to ignite the air-fuel mixture. I was just curious what the Ohms range would be on various contactor types. Your spreadsheet is bloody awesome work, keep up that level of attention to detail and you're going to have a killer wiring harness! Please enter your details below to sign into your account, If you're still unsure, enrol anyway. Myth 4: A stock H.E.I. PyQGIS: run two native processing tools in a for loop, Mike Sipser and Wikipedia seem to disagree on Chomsky's normal form. My question is how much current draw does it take to open that 24vac coil on the contactor? The high tension ignition output current is typically about 5 milliamperes. Using 4-amp-seconds per minute from above, 18000/4 = 4500 min. Ignition Coil (single oil-filled coil older vehicle) - 3 to 4 amps. F4i probably has 4~8 amps per coil (probably 0.5~1.5 Ohms primary resistance) they are switched for shorter period and use ecu as grounding point W Wee Todd Coast to Coast Jun 22, 2010 #3 https://www.applianceaid.com/ Appliance Repair Aid It's OK to talk to yourself.and OK to answer yourself. The question I have is is there upgrades that can be done to stock stators and rectifiers on older bikes that originally came with points ignition and 5 ohm coils so they can properly handle an electronic ignition upgrade without having to use resistors with 3 ohm coils? Sale ends todayGet 30% off any course (excluding packages). The solid epoxy, in comparison to oil-filled coils also eliminates the possibility of leaks. Stack Exchange network consists of 181 Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share their knowledge, and build their careers. See what I mean, Armour? Either 12V across a 3-ohm primary coil or 6-9V across 1.5 ohms in a ballast coil. I'm playing with the thought of installing the AMR monster ignition coil for a Raptor which seems more suitable. The fact that the duty cycle is low (20%) and that only one coil is firing at a time makes me think that would be ok. Am I right ? it requires a unique spark plug lead connection that incorporate a ferrule. Motor Vehicle Maintenance & Repair Stack Exchange is a question and answer site for mechanics and DIY enthusiast owners of cars, trucks, and motorcycles.

The large cap also offers extra space to host the coil, making the HEI distributor self-contained. ), Idle Speed Controller Power - 12v @ 4Amps, Idle Speed Controller ECU LSS - 12v @ 0 Amps, Igniter Trigger from ECU - 12v @ 0 Amps (negligible - pretty sure this is another LSS), Igniter Power From Relay - 12v @ 10-20 Amps (Read this somewhere, but i feel this is high). 4hp vs 18hp)? NOW the 18 Gauge Wire is rated at 20 AMPS THOUGH that same wire is DE-RATED by the Length. Without enough information, I'd say to figure 5A for total ignition usage. If your car uses a negative ground and you have a coil with primary and secondary terminals, the primary winding is connected to the terminal on the coil that is marked "+" or "Bat.". Posts. Any switch rated at 1A or higher can switch two of these relays on or off with room to spare. This firing ability also allows wider spark plug gaps-in the vicinity of 0.050-0.055-inch. Now if it was an AC circuit we'd get ole Nikola Tesla to give us an answer. Attached is what I have worked on there are 5 tabs (Connectors,Pricing,Tools,Wiring,For Sale) Look at the Wiring Tab. runs on 6 or 9V) that bypasses the ballast resistor when starting the engine, you could get higher amps (12V over 1.5ohms = 8Amps). 76 Posts. I = V/R. They range from two and a half to three amps. The average current when charging is 1/2 of the 16 amps, or 8 amps. Attached Files. First, you need to calculate how many amps does this heater draw like this: Current (Amps) = Power (Watts) / Voltage (Volt) In our situation this is: Current = 1,500W / 120V = 12.5 Amps Now we know that the 1,500W space heater draws 12.5 amps. If you use 3 Ohm coils then in comparison to 5 Ohm coils more power comes into them and as a consequence more power comes out of them. I know that the Peak output voltage in a ignition coil is between 10,000-45,000 V "Or so I heard" but how many amps does the ignition coil draw from the 12Volt side ? In effect, causing the HEI housing to act as a heat sinc. (Mild LS1 build). The coil itself is going to have about 1.5 ohms just sitting for your application.

If you don't run 12,000 RPM, then this number would be proportionally smaller. What are the benefits of direct ignition (coil on plug) system? CoilPack Power From Igniter - 12v @ 2A. The stock engine wire harness for my vehicle uses 12 AWG wire for ignition coil power supply and ground. Is there a general rule for determining ignition coil power supply current draw or is this more a function that is specific to each type of coil and engine design? Re: Dyna ''S'' Ignition - what coils are best/correct ? What you will see is that the current passing through the coil will rise linearly over the dwell period of the coil, then drop back to zero sharply, in a repeating fashion. But at high rpm, 30 degrees isn't enough: The faster the crank spins (the higher the engine rpm), the less time available for recharging the coil. I'm familiar with ohms law but have only ever used it to correlate/calculate Volts/Amps/KW conversions in 240 & 415v. All you have to do is to apply a 12-volt hot lead to the distributor and you're ready for the road. It wasn't all that long ago that GM engineers designed the original HEI system to replace the decades old points-type ignitions. I would size my wiring for 15 amps for both, 14 gauge wire. WHAT ARE YOU TRYING TO DO? Trademark Office. How many amps does a 12 volt coil draw using a 12 volt battery? It's likely personal opinion, but when a carb slide or cable sticks, or when I need to shut the bike off quickly in some sort of emergency, being able to do so with both hands on the handle bars - and not the front brake/accel hand having to reach behind and below me leg fumbling for the key - for me is useful purpose.
