I have a 1990 olds car and when I put the new battery in the battery warning light will not go off do I have a short somewhere.
because the car sounds like it needs more battery power. And where do I look for a short.

Do you have access to a voltmeter? If so, what's the voltage
at the battery terminals with and without the car running? You
might have something as simple as a bad alternator. Those
new style GM alternators aren't well put together and they
have issues with high heat. I went through a couple in Florida,
and there was nothing my rebuilder could do except redo
the work.

As noted, likely a bad alternator. Replace with a Delco rebuilt.

Please don't forget to check fuses and fusable links.. Also make sure the battery is fully charged when replacing an alternator..A weak battery has killed many a new alternator..
