Found out why the video did not work, the alternator must have been faulty as is failed today, dead short and burnt some wiring, had already tried the camera in my road going T2 and it worked fine, so can only imagine the one in the "black pig" was over voltage, that would explain the fuzzy lines on the screen before it turned off, so will fit the spare alternator I have in the barn, off the scrapper I think, but there must be another around some place, but can't find it, oh the memory, but have several other alternators about so will fit one of these in the air con pump place just for the winch battery, happy days, cant wait for the next outing,
