Every so often my rev-counter decides to jump to 3000rpm and stay there regardless of revs. A quick but strong smack to the binnacle usually convinces it to resume its normal duties. I think there must be a break or loose connection in the circuit somewhere inside. Has anyone else had this and how did you sort it? Anyone have a wiring diagrame for the connectors on the back?
I understand they are about £150 new from Alfa which I would like to try and avoid if possible, but have stumped up for bigger bills!
