Electric issue
Hi all, I have an electrical problem that I hope you can help with. When I turn the car off and remove the key the red “gen” light stays on, on the dash. (Drains the battery)
if I disconnect the battery, I hear a click, then if I reconnect the battery the red light is off.

i have only had this car for a couple of years.
it has had some after market adders. Here is a pic
let me know what additional info you need to help me resolve this issue.
Thanks

Try to isolate the problem. It could be a diode in the alternator. It could be the regulator. That "click" diagnostic you provided makes me think about the regulator. Only one needs replacement.

1. Attach a positive test lamp to a diode lead.
2. Attach the negative test lamp lead to the heat sink; the lamp should light indicating a good positive diode.
3. Check the other two positive diodes in the same manner.
4. Reverse the test lamp leads and again check the three positive diodes. The lamp should not light for a good diode. If it does light, that is your defective diode. Replacing the diode should resolve the problem.
If all the diodes check good, the problem is most likely the regulator. Your diagnostic makes me suspicious of it.

Update
So, yesterday I finally got back to work on the Olds. I replaced the alternator and the voltage regulator and also put on the correct connector to plug into my he new alternator. So far everything seems to be working as it should.
Ozzie, I didn’t try to figure what was defective, the alternator or the regulator..... but thanks.
When I looked up the costs, I decided to do both. 45 mins ( with one beer break) all was complete.
thanks to all the help guys
