ballast resistor help needed

discharger1332 said

i recently did the mp electronic ignition conversion to a 318 in a 72 dart. got it all tuned and running nice, after idling for a couple of min. it died. now it wont start at all. coil isnt putting out any spark, so i swapped it for another i removed from a running car w/ elec ign. still nothing? so now i figure maybee ballast resistor? not sure what to ask for at parts store, as this ballast came with the ignition kit? anybody know what ballast i need?

It would be helpful if you'd tells what it came with. These are easy to check, simply turn the key to run, and use a meter to check voltage to ground on both terminals (if 2 terminal) of the resistor. One should be "close to battery," and the other will be quite low, anywhere from 4-8 volts

You need good clean power from the ignition run buss, as well as a SEPARATE power coming from the IGN switch in start for the coil resistor bypass. Many of these cars are now suffering from damage to the bulkhead connector and other areas.
