hello all. I came across a 1990 XJ6 with 186,000 miles for $650 bucks today. Body is in good shape and there is some interior work that needs done. Mostly a torn driver seat and missing passenger carpet. The car had a dead battery and after giving it a boost I was able to drive it home. The engine sounded great and it had good power.

After the the short drive the car wouldn’t start again and the interior lights were dim. The car was able to start again while jumping and idled strongly. I noticed the following issues, 1. The trunk won’t open. Seller told me it opened with the button in glove box but did not. 2. Rear lights are not working although break lights and hazards are fine. 3. Interior dash board lights are not working although dash warning lights, (gas, battery, “lighting bolt?” Etc stay lit.

what this appears to me is that I need a new battery, and my guess is there is a fuse out somewhere. Any ideas on the trunk?
