2000 Pontiac Grand am battery light won't go off

Hi @nancers

Some things to check:

Check if 10A fuse #35 in the engine bay fuse block is OK

With the car parked, the handbrake firmly applied and the transmission in Neutral (MT) or Park (AT), start the engine and then use a voltmeter to measure the voltage across the vehicle's battery terminals. You should measure 13.8V. If you measure less than this then there's a problem with the alternator or the voltage regulator and that is why the light is on

Be safety aware as the engine is running

Here's an image of the charging circuit for a 1999-2005 Grand Am that may also help if the above tests are both OK. Perhaps check if the wire colours/terminals on the alternator (generator in diagram) shown in the diagram match the the wire colours/terminals what is connected to your alternator.
