F550 electrical gremlins
Ok, I have a 2012 f550 here at work and I got a weird problem. The truck just up and died on the guys, then re started, then died again, now it's dead. I can turn on the key, and the aux switches will turn on and off, but the radio, gauges, dome light, and door dinger don't work. I can push the power button on the radio and the clock illuminates, but the unit won't power on. The power windows and locks don't work, but the mirrors do. I have voltage in the cab and know it's to the ignition switch, does the BCM have power coming off of the ignition switch to start it, if so does it have a fuse and where is it. Any help y'all can offer me would be greatly appreciated

Check the BCM for water leaking on it, you’ll have to pull a plug or two and check for corrosion.

GOT IT!!!! Fuse number 18 was corroded and or blown. It looked pretty crusty, and it's in the lowest point of the fuse block, the truck is a mine truck so it is full of limestone dust and mud. But hey it's going again thanks y'all.
