Hi Alan, many thanks for the reply. I have bought a manual for the 1994 ST1100 but not being mechanically minded am very loath to even attempt this sort of fault finding. I did manage to change a cigarette power adapter over to a double USB for phone charging but with the wiring and panels put myself into all sorts of bother and 4 hours of tearing out the hair. I don't mind paying somebody here in Brisbane to look, diagnose and repair / replace but this is not in my level of expertise or should I say experience. I have only had the bike since December 2014 and still finding my way.
many thanks
