I have a 2012 Serrano and am having an odd and annoying electrical issue. After driving for an hour or two when I shut off the engine the 100 amp breaker to the coach batteries trips. I've had 4 "professional" repair places check it and they have no ideas. In their defense it only does it about 1/2 the time. I go to the battery compartment , flip the breaker and all is well.
Originally it would only trip when I used the leveling jacks but lately it will do it just by shutting off the engine. So I no longer think the jacks are the issue. I've replaced the actual breaker, checked all grounds/connections and have all (8) new batteries. House and chassis. Super annoying to say the least. Any ideas? thanks
