Hi all
Thanks very much for your prompt responses
Here is my update
Funnily enough my wife had said a couple of times that she could smell somthing burning after a long drive
But as I could not see anything I dismissed it
But she was right (as usual)
As following the very helpful post from Alanb i checked the em40 and found that it had melted the vb in positive plastic connector
so on monday i contacted Apuljack for a replacement and it arrived on Tuesday morning great service recommended
I fitted it today and everything is working as it should be bit fiddly took me about an hour
still could not find the split charge relay I think Robin Hood is right
Thanks again for everyone's input much appreciated
Barne
