Question about 1990 Oldsmobile Regency
Pull interior light fuse and the clock fuse, then disconnect the NEGATIVE battery terminal, and place a volt meter in between the terminal and the cable... There should be very little current. You can also wire a light in between the batt and cable, if no voltmeter is available.
Most common issue is diodes in the alternator. Alt can test okay on some tests, and still have an issue. Failed diodes leak power to ground.
So, keep disconnecting stuff until you get no voltage at the meter or light in series with the battery and cable...
With this method, you should be able to find the culprit.
