I spent a little time on my Avo 8 last night and saw from the prise marks around the case seal that it had been opened before, possibly by the previous owner.

A brief visual check didn't show any obvious damage or wiring faults but there seems to be an oily substance all over the rear of the switch assembly, I'm wondering if it might be the residue from some sort of swiitch cleaner used to clear a contact fault at some time.

I will try to clean this substance off and check for it's presence on the switch contacts. I have only Servisol switch cleaner here, is that suitable?

Cheers

Roger
