Re: 87 GTA will NOT turn off with key
could check if the alternator is backfeeding the switched
ignition-don't know about CS130 alternators,but the
older SI type need a diode or bulb in the turn-on wire
or they will feed voltage out that wire once rotating and
continue to power ignition if there is no diode or bulb
to block the backfeed.
