The electric fan that cools the radiator on my '73 has started running all the time when the key is in the on position. The previous owner had installed a toggle switch on the dash that used to turn it on and off, but it also operated on a thermostat. It used to go on by itself after the engine warmed up to a certain point. Any suggestions of where I should start my search to get it to not run constantly? It's probably not the biggest problem, but today it kept me from hearing my fuel pump clicking away, and I drove off with a busted pump. I didn't get far.

WELL, SINCE IT WORKS ALL THE TIME, GROUND IS GOOD; SO CHECK THE THERMOSTAT THAT CONTROLS THE FAN, REPLACE IF NECESSARY. P.O. LIKELY HAD SAME PROBLEM ,HENCE THE SWITCH HE INSTALLED. GOOD LUCK....JHRV8.

Use a continuity tester. When the engine is cold check to see if you have a completed circuit across the themostat, you should not have, as the engine heats up then it will become complete. Check your switch, again if you have a completed circuit in both positions it's NG. Brett
