ballast resistor - ignition system -An internal combustion engine uses an electrical spark to ignite the fuel mixture in the engine. At the center of this system is the ignition coil. The coil is transformer that induces a high voltage output from a low voltage input. The automobile ignition coil consists of two coils of wire wrapped around an iron core. Hooking up an ignition coil is an easy task that can be done at home with a few simple tools. Disconnect the battery negative - lead using a socket and ratchet. Locate the vehicle coil.
These coils are also filled with oil for temperature control. Look at the ignition coil. These coils have one large terminal for the spark plug wire that runs over to the distributor and two small terminals that supply power to the coil.
Connect one end of the spark plug wire to the large center terminal of the ignition coil. Connect the other end of that wire to the center terminal of the distributor cap. Connect the positive terminal of the ignition coil to the "On" terminal of the ignition switch.
Connect the negative terminal of the ignition coil to the coil terminal of the distributor.

You can actually hook your coil up backwards and it will still run. Make sure the coil you have is an externally resisted coil. If it is not, then do not run the ballast resistor. Spooner Clinton and koyotekiller like this.
Spooner Clinton likes this. If you run an externally ballasted coil on 12v for a long period of time it will get very hot and break down. I have had much better luck using coils that are internally ballasted, or say on them that they take 12v power.
Does the coil need 12v constant or just on start up.?????? I'd leave it at full voltage fyi MSD ign box operates at v Mallory ign box operates at v.
The ignition coil is the component that converts the 12 volt signal into the high . is a special resistor wire and is bundled in the wiring harness with other wires. automotive wiring diagram, Resistor To Coil Connect To Distributor Wiring Diagram Using a Mag Sporty with E-start Big Twin Honda 12V Basic Wiring CB
If it is electronic ignition with the external msd coil, you should not have to run the ballast resistor. I've used msd, mallory, and accell ext.
If you are running an electronic ignition conversion in a points type distributor, it will depend on the kit you used on if it will need a ballast resisitor or not. Some of the conversion kits have modules that will burn out if the coil has too much primary voltage and it is on without the engine running. Much like the way points do.
12 volt coil hookup
Lorodz, from your last question, I not sure you are clear on this yet. If ign.
Also, if performing a 6V to 12V electrical conversion, use of an in-line ballast resistor between the key switch and the coil in a 12V non-resistor coil setup is also. The automobile ignition coil consists of two coils of wire wrapped around an iron core. 40, volts or more can be generated from the 12 volt vehicle battery to. Older-model cars used the volt ignition coils to provide power to the spark plugs. They usually required only three wires: the spark plug wire, the power wire and the ignition switch wire. Connect one end of the spark plug wire to the large center terminal of the ignition coil.
The only time you need a wire from the starter is when the coil runs at reduced voltage after started. CommishMar 29, I'd contact the manufacturer which I don't think you named, for the wiring diagram that they want.

The Chrysler electronic ignition that I use does use a ballast resistor so just because it's electronic doesn't mean that one is not required. Of course it is not wired like the points system diagram above. I'd be afraid of frying the box before I knew what happened.
On points, they lived a lot longer at volts. That is why there is a resistor in the wire either a resistor wire or a ballast resistor, depending on the car. The problem with that is when cranking, the battery voltage drops to about 10, meaning the ignition saw about Reduced spark power at one of the times you need it most.
The wire from the starter sent full battery voltage about 10 to the coil for starting. Electronic ignitions control the voltage in the box and there are no points to burn with excess voltage. Each manufacturer has a different requirement, so do what Tommy says.
Lucie, FL. If you're using an internally resisted coil, then use a constant 12V to the coil. The coil will say that it's internally resisted.
Ignition coil circuit diagram The ignition coil is essentially a low voltage to high voltage transformer with about to 1 ratio of windings and voltage. Because the output spark is very much higher voltage (20,v) than the car battery (12v), . another question is does the coil run 12volt constant or it just needs to see but my '63 C factory wiring for the coil is a steel wire not copper. If your Ignition coil has the recommended primary resistance, remove or bypass all Attach the Ignitor red wire to the ignition side of resistance, or any 12 volt.
