Car battery draining in an 88 Oldsmobile Delta, has new alternator on it
For whatever reason my battery keeps draining in an 88 Oldsmobile Delta. The car has a new alternator, battery, & the starter has been tested as well. We put a disconnect on the battery as suggested by my grandfather, but the battery still drains when the car is shut off. When the car is being driven the battery light stays on continuously, & the battery dies within an hour of the car being started, (even when it's been on charge all night long) Any suggestions would be helpful, & appreciated
