I am having a bit of an issue with my truck, it runs and starts normally, just as it should, but when the key is not in the ignition the truck has to power to anything. Cab lights, headlights, clock, and locks should work without the key needing to be in the ignition. I believe this started a few weeks ago, I noticed the smell of burning and the cab filled with smoke, a few days before that happened I installed an (admittedly sketchy) inverter for AC power, I thought that was where the smoke was coming from, but it still works fine. Another peculiar thing is that the radio wont turn on, the lights on it work, but no display or sound. I thought it may just be a fuse or relay, but I cant seem to find any damage (although I havent pulled apart the whole dash yet). Has anyone else had this issue? Any thoughts on what to look for? Thanks.
