Deteriorated Insulation and resulting bare wires
When working around your coach be ever on the lookout for potential problems. One such is deteriorated insulation on electrical wires. The high heat of the engine compartment creates a harsh environment in which to survive. Try as they might converters additions/modifications and aftermarket products added will not always be up to par to survive.
Witness a few bare wires at the trailer wiring junction block as found. Rolling the wire between two fingers resulted in it all crumpling off.
