I reckon the cables are good, think the multiplug harness is corroded and the light is in poor nick as well. Cant get on original part anywhere apart from online but need sooner for a visual recheck on the doe.
I use it a good bit in the summer, nothing better than tipping over to the west for a few days, as long as you dont mind noise and not doing much more than 50mph.
All part of the fun. No hurry anyway.
You are so lucky having that gorgeous west coast to just nip over too.
Must hire meself one and come over for a road trip sometime.

Scotland west side is beautiful too, but if the weather is good, the midges come out in the squillion.

Do get that same problem?
