The power lead is the wire that goes through the distributor housing. On older vehicles, one end would connect to the points; not sure what it connects to in electronic ignitions. I think the other end goes to the coil. Apparently, that wasn't the problem. Good to read your Valiant is running again.Please define "power lead"?
Battery terminals can get a oxide coating that looks good but will create resistance. About 1958, GM introduced the spring loaded end .Easy to install and remove (until the tangs broke or corroded) but were notorious for leaving owners stranded. Just pulling, cleaning the post and inside of the end clamp would allow them to get back underway. Usually without even a jump.Well thats the thing - ive had them off several times - just never cleaned them!
Thought I was confusing current and voltage but a resistor does both....If the only function of the resistor is to extend coil/points life, then can I run a 6v coil or other heavy duty coil and bypass the resistor entirely? Do I risk frying anything else if I run the system at full voltage all the time?"
