Only 2 Davie?-I went through 5 in one holiday on the ST4S, they all overheated-hot enough to burn your fingers-we never did manage to find out what was causing it so chopped the relay fitting out and replaced with nice beefy 888 one-hasn't given a moments trouble since.

Excellent, thanks. Some more stuff to try. I haven't had a chance to look at it yet, i'll let you know what it was in the end.
