Our 86 Oldsmobile Toranado’s battery won’t hold a charge longer than a couple of days. We’ve replaced the battery, the altinator, and the altinator plug - help! What wrong?! Thanks for any advice.
Something is on. The first thing I would do if the car has a light bulb under the hood and trunk, is to remove them and see what happens. Look at the taillights and see it the break lights are staying on after you have exited the car. Interior lights should be off, if this vehicle has the delayed off interior lights, make sure they are turning off. Return to the car a little later and check it.
