Hopefully you don't have my problem. The light works exactly opposite from what it is supposed to on my 72. As long as the engine is turning the light is on. As soon as it stops spinning the light goes out. I've had the charging system checked and it works fine. It's just that the light at night drives me crazy. I have wondered if the wires for the alternator plug were put on backwards???
Anyway good luck.
