Thanks guys
I have just parked it for the moment. While the clutch was apart for the second time Terry noticed the play in the primary gear. I measured it and it was 30 thou. Could that be enough to cause this? Anyhow, after the head gasket, 2 broken clutch plates, a painful electrical problem, radiator overheating & an alternator that was for most of the trip reading 12volts, we have come to the conclusion that it needs a full rebuild by someone that knows what they are doing, not me. I am sorry for the others that had to put up with our problems on the trip. Also, we owe a special thanks to Terry, as he stayed with us for another 2 days to try to get us home.
Mazy's battery is the same one as The Red One's. It is an AGM dry cell NS50P. Mazy has never had a charging problem, it reads 14.5volts.
I changed the alternator during the trip as it went from 13.5 volts to 12volts. After that it went from 13.5 volts for a while then went back to 12volts, slightly annoying.
I swapped batteries with Terry on the last day, & voila ! It was back to 13.5v. I dont get it, is the battery capable of drawing the voltage down from the alternator if it is faulty? I have no idea. Also, up until the last day it started the moke & ran a fridge. Something to ponder.
Thanks
