1989 Other Oldsmobile Models will not hold a charge

Hi there,

Check for battery voltage at large terminal on alternator, No voltage, problem between battery and alternator, Charge battery and load test, this will give true indication at to battery condition, (new cheap batteries often fail this test) Remove battery Pos cable, hook up Amp meter between battery Pos and cable, with key out and doors closed there should be only about.1 -.2 Amps, anymore and there is a current draw that will be causing the battery to go flat.
