How to replace a ballast resistor?
Steps
- Before you go to the trouble of replacing the ballast, you should determine if a bad ballast is indeed the likely cause of the problem.
- Remove the lamps and place them in a safe location.
- Turn the light off at the switch, as well as at the circuit breaker. ...
Do I need a resistor for my ignition coil?
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. So does your application require a ballast resistor? Quite simply, if your distributor has breaker points the answer is yes; if not, the answer is no.31-Aug-2011
Why do some ignition coils need ballast resistor?
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.09-May-2021
Can I bypass ballast resistor?
Yes, unplug both connectors from the ballast and put your jumper between either of the blue terminals and the terminal for the brown wires. Me personally, I would cut the resistor connectors off and just solder the wires together.29-Jul-2013
What is the difference between a ballast and non ballast coil?
A ballast coil is designed to produce the same spark output, but with only 6 to 9 volts on the input. With a non-ballast coil, the input to the coil is the same, 12 volts, whether the engine is running, or being cranked by the starter motor.
How do I know if I have a ballast resistor?
To test your ballast resistor you need an ohm meter or multimeter set to ohms. Remove the connectors from both sides of the resistor. The ohms should read between 1.8 and 5 ohms. You should be getting 9 volts to the positive side of the coil.
How do I know if my ignition coil has an internal 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.18-Oct-2021
Do I need a ballast resistor with MSD ignition?
Late-model electronic ignitions or an MSD Ignition do not require the ballast. If you are looking to upgrade your stock coil, or want to compliment the performance of your MSD Blaster Ignition, MSD 5, 6, or 7, the Blaster Coil line is the right choice. Our Blaster Coils are designed for improved spark output!
Can you hook up a ballast resistor backwards?
Resistors lack polarity. There is no backwards.29-Apr-2016
How do you connect a coil to a resistor?
Strip the end of the positive wire from the ignition, and connect it to the positive end of the resistor. From the other terminal on the resistor a wire goes to the positive on the coil. Make sure to attach securely to the connecting terminal, by wrapping the wire around the post and tightening with a screwdriver.02-Feb-2011
Do I need a ballast resistor with HEI?
Whats the application? Generally speaking (and every one i have ever delt with), an HEI does not need a ballast, they use 12 volt switched ign for power. So, the easy way to bypass the ballast system would be to run another wire from the ignition switch that powers when you turn the key on to your HEI unit.22-Mar-2013
What ohm coil do I need?
Measuring Coil Secondary Resistance: For best performance, coil should have 7K Ohms or more secondary resistance. To measure secondary resistance: Label and remove all wires to coil ( + or - ).
What Should the resistance be on a ignition coil?

What is a ballast resistor?
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.
Do you need a ballast resistor for an ignition?
Electronic ignition systems, whether factory Mopar or aftermarket, don't utilize breaker points, thereby not actually needing a ballast resistor to control amperage through the pickup coil. Quite simply, if your distributor has breaker points the answer is yes; if not, the answer is no. Additionally, what does a ballast resistor do in an ignition ...
Do you need a ballast resistor for a Mopar pickup coil?
Electronic ignition systems, whether factory Mopar or aftermarket, don't utilize breaker points, thereby not actually needing a ballast resistor to control amperage through the pickup coil. Quite simply, if your distributor has breaker points the answer is yes; if not, the answer is no. Also to know is, do you need a ballast resistor ...
What is a ballast resistor?
A Ballast Resistor is an electrical device that reduces voltage to the coil so that more energy is available for the spark plugs during starting.
Why do spark plugs need less energy?
Because the starter motor draws a huge amount of current from the battery, the spark plugs are left with less energy to create the spark. This is worsened in colder starting temperatures or when the starter motor is worn, when even more energy is drawn by the starter motor leaving even less available for the spark plugs.
Do you need to change ballast coil?
If you have a ballast coil installed with a ballast resistive wire or a ceramic block then you can keep the coil as it is, there is no need to change it BUT if you change the coil you do need to match it to a ballast if one is present and not bypassed.
