Never had an issue with EHU  lead before & hope my update got through as internet dropping out but the was an issue with the electrics in the garage, tested the socket I was connected to and found that 1 red light showing in tester indicating fault, tested another socket in kitchen tester all ok, checked socket in van with tester sand all ok, checked rev polarity light on sysyem.under seat and it wasn't on.
So in the end all ok

Cheers

For other readers to note:

The only time I've had the reverse polarity light on the psu come on at home, the fault was an open circuit earth conductor in my hook up lead. This was potentially a life threatening fault as it would prevent the operation of the residual current device on the input of the 230v if an earth bonded metal surface became connected to the 230v live.

I located the fault in the body of the cable. The earth conductor was not continuous. Two ends of the conductor butted against each other and were sealed in the cable sheath during manufacture, sometimes there was continuity but most times not - I'd been using that cable a long time so was lucky no other fault had developed with the wiring in the van......
