Measured voltage at the RV end of the cable is 185 across the outside pair, and 88V on the 120V legs. I'm losing 60V on the 240 and (consistently), 30V on each of the 120V legs, over a 25 foot cable.
Is this just a bad power cable, or do I need to look for some other issue? When I got the RV, there was a gap of about 1/2 inch between the end of the outer cable jacket and the male plug, so I had my electrician replace that plug at the same time he installed my 50A circuit, but perhaps some evil lurks in the heart of that cable anyway?
Where did you physically measure this? The incoming cable goes into the switch box. Was it measured at the point where the wires are terminated? Was the wire isolated from the coach by turning off the main switches? Where was the meter probe grounded? This information is required to troubleshoot the problem. I would look at the repaired cable plug first if everything worked OK before that was done. Kinda sounds like a neutral switched with a hot in the plug.
