Thanks

The check engine light comes on after you turn the engine off … keys out of ignition switch?

I have seen alternator warning lights come on dimly after ignition switch is off if the diodes are bad. Could the alternator be wired into the check engine light?

For some other ideas, here is a link for 81 Camaro. Should be similar for 81 Avanti.

Thanks the gauges say its charging its not on when its running just when shut off and does not go out had to disconect the battery glad car runs when ground cable is removed so I don't think its the alternater.
