I recently upgraded to an MSD ignition system and at first my car would not turn off. So after installing the small diode I get with the kit, I can now shut the car off but the generator light stayed on while running. When I took the diode back out to double check, the car ran fine and the generator light was off while running but would not turn off again. Any suggestions??

Thanks

Are you sure you put the diode in the correct way?
I also had the run-on problem with mine after installing my MSD but the diode did the trick for me.

I tried several different ways, but this way it still shuts off. Everything works like it did before except for while running the light stays on. As soon as i remove it, the car won't turn off but the light will be off while running. Does this diode maybe act like a bit of a resistor in a way, making the idiot light think that the alternator isn't charging enough??

Thanks,

Maybe the alternator/regulator isn't working right. Voltage out of the F terminal should be near equal to voltage out of the back of the alternator (Battery). If the 2 voltages are equal the light goes off.
