Bed alternator or battery


That sounds like you might have a grounding problem in the main circuits, but as stated by Fred it could be a charging system problem, low or unstable voltage can cause all kinds of electrical system malfunctions. Get it checked over professionally.

Bed grounding in the circuit how to start to find the right circuit then how to start locating the grounding


There are a lot of grounding points on this vehicle, I would suggest you get a shop manual, one that has a component locator and flow chart to help you with this track down.
