ballist question(need help)

[jiw700]

with the key in on position, is normal for the ballist to get hot. also how much voltage is normal at coil with the key on,not running(just trying to get things right before i get it started for the first time........i'm getting nervous)

I have had balast resistors get hot, and so has my budy who has a '70 dart.

I don't know how normal it is, but it has happend to my vehicles befor.

I think it's pretty normal. I've been using MSD for years now, but seem like the ballast used to stay hot.

they get hot.A little over 6 volts not running,

Start mode, almost 12 v, key on, about 8 v. Turn the key off, you are burning the points.

thanks for the info. mines less voltage, battery could probably need a good charge.

why i ask is i just put in MP electronic kit

different model coils have diferent impedence (ohms)so voltages vary across coil or ballast resistor.as rpms increas coil impeadence goes up causeing coil voltage to rise and resistor voltage to go down.just letting people Know the numbers very a bit dont get hung up in decimal points
