Paul, Fred, Ed, what both of you are saying makes sense, ( house power shorted ). The big
concern now that time is passing by why would anyone at a mfg level put a plastic J-box above
or right on top of the hot discharge side of a turbo charger with engine encased under the house.
My little motorhome had a similar occurrence happen and caught fire. With membership
owning Beaver motorhomes there now seems several problems mfg wise starting to occur.
The forum has pointed several out. But this one stands out if correct diagnostic, that will burn
down the house. Note: turbocharger under load all day if you look at your turbo in evening
you will see dull orange color of the turbo housing, yes the turbo housing discharge side is
hot. Next point of concern debris falling in and around turbocharger will melt or burn. Paul
Looking at that one part number ( last post ) will verify if aftermarket add on equipment has
been and is related to the box. Dave Atherton Retired Cat Mechanic
