Why does Mopar use ballast resistor?
Why does Mopar use ballast resistor?
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 are ballast resistors and Mopar electronic ignition?
Ballast Resistors and Mopar Electronic Ignition Conversions… type ignition to Chrysler electronic ignition. The kits typically included a new distributor, ECU control unit, a ballast resistor and the required wiring harness. worked fine on either and were interchangeable.
Do you need ballast resistor for MSD Ignition?
Late model electronic ignitions or an MSD Ignition do not require the ballast If you are installing the Blaster Coil with the stock points ignition (Figure 1), MSD Blaster Ignition or an MSD 5 Ignition Control (Figure 2), the supplied 0.8 ohm ballast resistor must be installed on the coil positive (+) wire.
How to test a ballast resistor with multimeter?
Shorted is not good, but also near impossible to achieve. To test your ballast resistor you need an ohm meter or multimeter set to ohms as previously suggested but you really need to remove the connectors from both sides of the resistor. I believe single should read 1.8 ohms and dual should read 1.8 and 5 ohms.
When do ballast resistors need to be replaced?
If the voltage reading is more than 14.0 volts at any RPM level, the voltage regulator likely needs replacing and/or a 1.4 Ohm ballast resistor should be wired between the coil’s + terminal and the red HotSpark ignition wire. Too much voltage can damage the ignition module and other electronic components.

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?
