How many volts does a ballast coil need?
A ballast coil should read around 1.5 Ohms or around 6 volts. (maximum 3.4 Ohms is ideal for our systems) Which coil should I use if my car has a ballast resistor? Using a non-ballasted coil would mean that you are running a 12v coil on a 9v feed, resulting in a weak spark.
When do you use ballast in ignition system?
Traditionally, ignition systems didn’t use a ballast, meaning that the ignition system used a 12v coil with a 12v feed from the battery via the ignition switch. This system is fine when the engine is running, however can be problematic when starting.
Can you run a non ballasted coil on a 9V feed?
Using a non-ballasted coil would mean that you are running a 12v coil on a 9v feed, resulting in a weak spark. You can however use such coils provided you remove the ballast resister. Never try to run a ballasted coil when a ballast resistor is not present in the ignition system!
Is the MS 6 volt coil a ballast resistor?
As far as I know I do not think ms 6 volt system uses a ballast resistor. It should whether it be an actual ballast resistor, or a primary resistance wire. On the coil small terminals are there two wires on one terminal, and one on the other leading to the breaker points?
Can a 12 volt ignition system work with a ballast resisted ignition system?
Running a 12-volt coil on a ballast-resisted system will produce a very weak spark – consequently the engine won’t run too well. Running a 6 or 9-volt coil on a 12-volt system will produce a healthier spark but will burn the coil out real quick.

How does a ballast ignition system work in a car?
Ignition – Ballast ignition systems. When you hit the starter button/key, a massive drop in available current to the coil occurs as the starter motor does its thing. The colder the weather or the more worn the starter motor, the more current it draws, the less there is passed to the coil to instigate ignition.
