ACE Outside electrical outlet shorts when wet
I was washing off the roof of my ACE 29.4 and when I was done I noticed that the shore power was off and had tripped the breaker. What I have found out is that the outside electrical outlet is not sealed well at all and water from the roof dripped down and into the outlet thus tripping the breaker.
I took the whole outlet apart and resealed it properly to keep the water out of it.
So, check your outside outlets to make sure that they are sealed properly and that water dripping down the side of your motohome won't get into them.
