Sorry to hear this Steve...don't ya just love it!
I haven't had the problem of frying the reg/rec, but this thread where I had a problem with a non-charging battery icludes some good info on how to determine if it is the RR that is knackered or summut else!
I may also have a spare RR lying about if you want to try it?
