Ok on my dads car which is a 96 nissan 240sx. Which is stock. The tail lamp fuse keeps popping I've been trying to locate where there could b a short but nothing I was wondering if mayb anyone on here can help me try n figure this out to where to possibly look or solve this problem. Would an aftermarket radio cause this? The radio has been in for quiet some time. So I'm kinda stump. I hate electrical stuff. If u can help me out I would appreciate it.
