I chased my problem for about 6 months. Couldn't figure out what it was until one day I had parked my truck and was sitting in it reading the manual and all of a sudden the dome light came on. So pulled the bulb out. No luck, still something was draining the battery. My truck is a work truck that plows and pulls a lawn trailer so it doesn't run on a daily basis at times. Was working on my equipment another day and heard the chimes go on for no reason. Took the fuse out for that. That seemed to help some. Then the locks, radio and gauges went wacky and would turn off for no reason and then come back on. Finally changed the instrument cluster out with Circuit Board Medics. That has fixed every single problem I was having. Here I was checking wires, connections, checking voltages and all the while it was the instrument cluster. What a simple fix for me for what I thought was multiple problems and hours of checking things that weren't bad.
