Hello, thanks for writing in about your Oldsmobile 98. You need to have the charging system checked to see if the alternator is charging the battery. You may have a blown main fuse if the alternator is proven to be charging but doesn’t get a charge to the battery. Have a certified technician, like one from YourMechanic, diagnose the issue with your battery if you’re unable to pinpoint the issue yourself.
