The Flame Thrower 40,000V coils have internal resistance rated at 1.5 or 3.0 ohms. I have a factory tach that I still wanted to work so I kept the 1.5 ohm pink wire in place. In my research I have read on here some of Bubba's threads and posts recommending 3 ohms resistance in the 12 volt+ feed to the coil. Requires 9 V supply, with ballast resistor of 1.8 ohms. I have a 1986 Glastron with a 3.0 Mercruiser. Iput 4000 miles on the clock in the last year. Thing is someone says I need a ballast resistor or I may blow up my tacho?? A “standard” coil will have an internal resistance close to 3 ohms on its primary windings. The coil for a ballast ignition system will have a primary winding resistance between 1 and 2 ohms. First, the ballast resistor is the long, white ceramic thing attached to the left side of the coil assembly. You can detect the presence of the resistor by measuring the ohms of primary side of the coil (terminal 15 vs. terminal 1). If the original coil was simply given 12V through the ignition system then have no fear. It say's OEM replaceent, it also shows a 1.76 ohm resistance built in primarily.

What I am wondering is if the 1.6 ohm coil will have sufficient output for normal running with reduced voltage supplied to the primary due to the 3 ohm resistor? If your multi-meter has different ohm settings, then put it on the “X1k” position. Secondary resistance - 8 - 10,000 ohms. The alt wire is only 12 gauge, will change this to 8 or 10 gauge for permanent use. Ballast Resistor in Fluorescent Lamp That is what I bought but it only drops the voltage maybe half a volt. Our Ballast Resistor is designed to be used in conjunction with our available External Resisted Ignitions Coils. Why? Can I remove the ballast resistor and run a 3 ohm coil? Tech Question Erik Bakko, Brooklyn, NY, 72 Dodge Swinger 318ciDear Mr. Mopar Guru,My ballast resistors have an expected life span of 3 months in my Dart. A ballast resistor is a resistor inserted into a circuit to compensate for different changes. These Summit® ballast resistors are perfect for protecting your points-style ignition system. I've blown up two of these, one from not having a matched coil and ballast resistor (the total series resistance from the input of the ballast resistor to coil terminal 1 MUST NOT BE LESS THAN 3 OHMS OR IT IS LIKELY TO COOK THE PERTRONIX), and second one from just being a dope. As Rob says, surprising an unballasted 1.5ohm coil hasn't cooked but maybe you haven't been on any long journeys. But check and double-check. The solution to this problem was the ballast which reduces the voltage down to the 6-9 volts the 1.5 ohm coil prefers. Primary turns - 240. Check the multi-meter ohm setting. For what it's worth, I have been using a ballast resistor on my CD175 for a few years now with no problems at all. Skip to main content. The coil is from an early 50s Ford 2 ton it tested at 1.8 to 2 Ohms, the high tension wires are used, the ballast resistor was used on this engine, prior to its being parked for 6 years. Another approach is to eliminate the ballast resistor altogether by using a replacement coil with 3.0 ohms of resistance. Basic function: the ballast resistor is a resistor contained in the primary ignition circuit wiring that lowers voltage after the engine is started to reduce wear on ignition components. Total about 3 ohm total If I keep the ballast resistor then I think I buy a 1.5 ohm. It can either be a ballast resistor or a resistor wire. Its also surprising that the Ignitor worked satisfactorily … The ballast resistor. In order to maximize the coil's output during starting, ballasted ignitions have a ballast bypass which sends 12 volts directly to the coil during startup. About the Product. Unsure how to tell if your Classic British Car has a ballast resistor or not? By the formula I found (Ohms x 2= volt drop) a 1.25 Ohm resistor would work. Two commonly available 3 ohm coils are the Napa IC14 and the Pertronix High Voltage 40511. According to the paperwork that I have for my Lumenition kit, the power module is suitable for coils or coil/ballast combinations of not less than 3 ohms. A set of points would die in about a day with that much current. Order Ballast Resistor for your vehicle and pick it up in store—make your purchase, find a store near you, and get directions. When I changed to 12v I kept the old coil and fitted a 2 ohm resistor in series. Ballast Resistor.
