many thanks for this
that is great to know and i will certainly check these points on the bike. Really useful as i had started looking at earth points near the lights themselves and all appeared fine.
i will get the left panel off and have a look
there are a few points at which cable ties have been used.
these are the OEM lights and bars fitted by a Honda dealer (unfortuantely has now since sold the business)
cheers for info and advice
