1. It is an everyday driver, runs very well. I just put a new battery, voltage regulator, and reman alternator. The problem is after I turn off the key the alternator light comes on and stays on until I start it back up. I checked it and it is charging (13.5 volts). I also took it off and had the store I bought it from check it.
2. A bad cell can cause the generator/alternator to overcharge the other cells which will trigger the generator light in the speedo. With the key in the OFF position (remove it from the ignition to be safe!) and the negative cable removed from the battery (keeping the positive cable still attached) connect a test light between the negative battery post and the disconnected negative battery cable.
3. This happened when the key wasn't even in the ignition!! Somehow I'm powering the circuit with the generator warning light even when the key is out of the ignition?? This circuit should be cold unless key is in run position. I found if I unhook any of the wires from the alternator, the relay 'un-clicks' and the generator light goes out.
4. 62 Impala generator light stays on after key is switched off, just had the generator front bearing and rear bush redone buy an auto electrician. Put the generator back in the car and now the light sta read more.
5. Battery light stays on when car is off!!!! I am the original owner and have about 165k miles on the truck. I can honestly say that I have had next to nothing go wrong with my truck minus brakes and normal maintenance items.

woudl see if the belt is tight and is NOT slipping. If you haven't

bought a new belt lately, its a cheap investment. If the belt is

tight and the alternator light stays on, take the car to Autozone

or Pep Boys and have it checked while on the car. If you have a

multimeter you can check it by seeing how many volts are comign out

of the alternator by placing the leads on the alternator to see

what current is being generated by it. Anythign less than 12 I

would buy a new alternator. Most cars need over 12 volts to 14

volts to operate. Most of my cars run 13-13.9 volts. Also, check

the voltage regulator which is located on the fire wall below the

left windshield wiper. This a cheap part which often fails on that
