Frequently Asked Questions (FAQs)
1. What does a resistor do on a ignition coil?
Generally, an ignition ballast resistor is placed between the primary source of the ignition coil and coil stud. It reduces the failure risk of the ignition coil. When the starter motor cranks the engine, the ignition ballast resistor helps to reduce the coil voltage and coil current.
2. Does an ignition coil need a resistor?
And while ignition coil life may be compromised without a resistor, the additional secondary voltage (at the spark plug) is increased which generally improves power.
3. How do I know if my coil needs a ballast resistor?
To check if there's an internal ballast resistor in your coil, there are two things you need to do: 1) remove any cover covering up your coil, and 2) check if your ballast has 3 wires coming out of it. If the ballast doesn't have the ballast resistor built inside, then there should be three wires coming out of it.
4. Do I need a ballast resistor with electronic ignition?
The electronic ignition systems don't use breaker points, so they don't need a ballast Resistor to control the pickup coil.
