Question about 1988 Pontiac Sunbird
We have replaced the battery and the altinator. Checked all known fuseable links and have power before and after them. The battery reads 12 volts, but the interior switch reads 10 volts and the new altinator isn't charging the system. Although the car runs as long as no other electrical devices are used ie. turning signals, lights, cruis controle, windows, radio ext. We are looking for a charging system wire diagram for a 1988 Pontiac Sunbird Turbo.
Here ya go check for power to the alternator good luck ............ justuscc Charging & Starting System Wiring Circuit - VIN K
