What does a Mopar ballast resistor do?
In simple terms, the ballast resistor in a Mopar limits the amperage, or current flow, through the coil while the engine is running, thereby extending the life of the coil and breaker points of the distributor.
What happens if you don’t use a ballast resistor?
If the ballast resistor is not working properly, the vehicle will not start. Since it is an electrical system, it is something best left to the professionals to handle. The only way to have the vehicle up and running again is with a ballast resistor replacement.
Does a ballast resistor reduce voltage?
The ballast resistor, supplies the needed voltage during the start up, and then immediately after the arc is established, it reduces the voltage in addition to regulating the current flow.
Why is my ballast resistor smoking?
the ballast WILL heat up. Any grease, oil, etc WILL cause it to smoke. IF you have points it is VERY HARD on them to leave the key on for a length of time.
How much does ballast resistor drop voltage?
The external ballast resistor (or resistor wire) will provide an additional 1.5 ohms of resistance. Current flowing through the ballast resistor will create a voltage drop and thus lower the coil’s operating voltage to something between 6- and 9-volts.
Does a ballast resistor get hot?
Re: ballast resistor getting hot Old style Ballast resistors get hot, its the way they work and why they are mounted the way they are. Basically if you were to remove the filler you would find a wire coil, usually a fairly thick gauge and the current flowing through this is creates the resistance.
Should my ballast resistor get hot?
What is the ballast resistor on a Mopar coil?
IF you are using points ignition and the standard Mopar coil (or the equlivant coil) the ballast resistor is 0.5 ohms. IF you are using the Mopar electronic conversion ignition system (“Orange box”) the ballast resistor is 0.8 ohms. IF switching to a High Voltage coil, the ballast resistor MUST BE MATCHED TO THE COIL.
What is the ballast resistor on Orange Box?
IF you are using the Mopar electronic conversion ignition system (“Orange box”) the ballast resistor is 0.8 ohms. IF switching to a High Voltage coil, the ballast resistor MUST BE MATCHED TO THE COIL.
What is the ballast resistor for points ignition?
it depends on which coil is used. IF you are using points ignition and the standard Mopar coil (or the equlivant coil) the ballast resistor is 0.5 ohms. IF you are using the Mopar electronic conversion ignition system (“Orange box”) the ballast resistor is 0.8 ohms.
What kind of resistor does a Mopar Blaster use?
One of my DC/Mopar Perf charts says use .25 Ohm resistor with Orange box & the Blaster coil ( Blaster 1??) sold by Mopar Perf. Click to expand… What was the “cure” – a new distributor/oil pump drive gear?
