Hi
Thanks for looking. It has a mushroom emergency stop switch on the dash board but has two black boxes mounted near the batteries, which used to click like a relay. I spoke to a 'stagecoach' mechanic and he suggested that because it was a PSV, these may have been fitted as a 'safety' relay for each battery, by the operator, which is why I cant find any reference to them anywhere. He said he had known it before and this would also cause the faults. He also suggested 'shorting' the relays with a 30amp fuse. Not sure about that but its another avenue to explore.
Once again, thanks for looking
Steve
