Our coach has 60K and until now no electrical issues. Suddenly the front set of 4 incandescent lights is dim when initially turned on and then the breaker (near the big breaker set/box in the hall area) shuts them off and is warm to the touch. Clearly there is a short in the circuit but the only electrical thing I have done recently is install a satellite dish and a new step motor. Any ideas of where the short/issue might be? Could it be the screws from the dish install penetrated a wire in the ceiling?

I can find no wiring diagram for this circuit in the owners manual.

Thanks for any thoughts.

(other than that she's cherry!)

I would back the screws out in the dish and see if it holds then need to think about to get to that wire to repair it

It seems odd to me that wiring such as this would be so close to the roof shell--the screws are only about 1.25 inches long. What I was thinking about doing was to check voltage at the dish when the light switch is turned on--I should see a reading if that is the issue right!

If it's grounding or shorting you might get a reading or even get popped just don't try it in the morning with a wet roof, that is short screws you figure 3/8 inch for the base and the sealing tape that wire might be pinched in the roof sheeting and up to the top or just sitting on the top side of the chase
That would be my luck too put a single wire in a 1 acre field and I will find it digging

If the problem started immediately after the changes that you made it would implicate your work however if all was well for a time then likely it has to do with the lights that dim.

With the breaker heating as described you are likely dealing with a short.

Good luck.

Thanks for all the suggestions and interest. I hate to backout the screws that are now so carefully covered in roofing sealant, so that will be last resort. If that is the cause then like was said that was a highly unlikely/unlucky point to put a screw.
