Our motorhome is parked up and plugged into power, all 240v devices are working correctly, no apparent problem.
This afternoon was checking tyre pressures and picked up a small shock off of a steel wheel rim, first for me getting a static electricity shock from a vehicle chassis. While adding air and checking tyre pressure again received more shocks but they increased in power and were becoming quite sharp.
One shock was a little like the shock (I think 60v) from a phone line, well it was 35 years ago anyway. So decided to try to measure if there was any AC power through the wheel rim, it measured 80v.
Got wife to switch the mains off and the reading dropped to 18v, switched on again back to 80v.
So a question. Is there a shortcut to where to start looking for the problem or is it a case of starting at the 240v input socket and going through everything from there?
I was involved with general vehicle electrics for 20+ years with own garage workshop and have rewired a couple of houses, but wouldn't call myself an electrician.
Any help gratefully received
