Multiple electrical failures
I have a 2012 Daybreak on a Ford chassis. I have a parasitic draw of .5 amps. I can eliminate the draw by removing two mini fuses located under the dashboard on the driver's side. These fuses are #4 which protects the instrument panel cluster and #16 which protects the body builder battery feed.
In addition the following lights don't work: tail lights, license plate lights, running lights, instrument panel lights, parking lights and the map light. The other lights work normally. Testing showed I could vary the amount of parasitic draw by adjusting the dimmer switch for the instrument panel lights. Adjusting the dimmer to its lowest setting reduces the draw, but does not eliminate it.
I took my MH to the Ford dealership. They've had it for five weeks and have been unable to solve the problem.
Can someone tell me what the body builder battery feed is all about. What is its function? Because all these symptoms appeared at the same time it seems there must be a common cause to all the light failures.
