My 86 Grand Wagoneer doesn’t seem to want to hold battery voltage. I put a new battery in, new alternator, and a new starter. I also repaired a ghetto splice in the wire from alternator to the starter relay. Still no help. It has after market headlights (true LED modules) that werenon it when I bought it. The headlights stay in bright only at the moment, and the rear hatch window is stuck in the up position. It also recently began to read only high on the oil pressure gauge. Not certain these are related to my battery voltage problem at all. But as of right now I’m at a loss. Any ideas?
My car has an automatic transmission.
