I am having problems getting my 1 wire 12v alt system to work. It runs fine for a while ( 15 minutes of driving) then dies. The internal resistor coil is very hot. I have a walcks wiring harness that I started with and then changed out the electrics to a 1 wire alt. I have read up a lot about issues relating to changing over to a 1 wire alt system and think it is set up right. I am running a wire on the pos side of the ammeter back to the positive lug to the battery. I am using a solenoid and a key switch. I checked the ohms on the condenser and that looks fine.
I am considering using an external resistor also to the mix because of the coil overheating.
I know I have 12 v at the positive at the coil when starting but haven't looked at the voltage at the pos+ side of coil after it is running. I have gone over fuel related issues and think that it is o.k. Even thought it might be vapor lock issues but I don't think that is it. My main clue right now is that darn hot coil.
Thanks,
