Hi all, first time poster here. I've got an 89 D150 that I've been trying to get up-to-snuff and I've got a battery drain as long as I've got a fuse in the circuit that runs the interior lights, dome light, etc. I was just wondering if there are some easy things to check before I really start yanking things apart. I'd also like to know just what all is included in that circuit, if anyone could be so kind as to tell me. Thank you so much in advance.
