ballast resistor getting hot

[helopilot]

Put a new ballast resistor on the car today. It worked great for a bit then the car died like a switch had been thrown. Felt the BR and it felt fairly hot. The car sat for a while and then it started back up. Did the same thing over again. Any ideas? Car has new cap rotor points condenser. Additionally I have put a new alternator and voltage regulator.

Check the output of the VR. Maybe it's letting too much voltage to the BR. Check voltage at BR, see if it's too high. Was the old BR bad? If so, was it because it kept overheating?

Where is the best place to check the voltage from the BR? Do i check that at the Batt terminals?

Check the voltage at each end of the ballast resistor (BR). Put the black lead of your volt meter (VM) to a solid ground on the chassis, and put the red lead on one end of the Ballast. Write down the reading you get, then move the red lead to the other end of the BR (while keeping the black lead of the VM grounded) and write down the reading you get there. The higher reading is the input voltage TO the BR, the lower reading is the output voltage FROM the BR

Thanks,

I'll try that tomorrow.
