318 Wont start unless I jump out the ballast resistor.

Iginition switch seems like a likeley suspect, as it's the only part left in the ignition system that i have yet to change.

I love electrical problems....Actually I'd rather stick a screwdriver in my eye.

On a brighter note I just got off the phone with a guy who is gonna delver a 360 to my house tomorrow for 80 bucks!
It has a spun rod bearing but for the price i couldn't pass it up.

Back to the switch, Is there any way to jump it out and test if that is the problem?

Thanks again.

hehe. the whole idea of the ballast resistor is to have an extra boost when startup.. misunderstand me right. the coil is originaly ment to run on 6-8 V.. u have the ballast resistor in there to make a current resistance that will take down the 12V from battery U = R * I... if the current to coil was 1 amp the resistance should need to be 7 - 8 ohms... ok the idea behind all this is that when you are cranking the engine the ignition switch give 12V directly to the coil as a startup boost.. (this aint directly truth since the starter wil draw the voltage down to maybe 10V)

Ok back to your question, u just have to hotvire a cable directly from the starter relay and to the coil.. this wil give u the same voltage under cranking as the battery have. (i beleave its the same output on the ignition svitch as originaly used but a different wire)
