Took the bike to the dealer today for state inspection and of course it failed because of the fuse problem. I expected that and wanted to see if there were any other problems. There weren't.
The dealer can't service the bike until Sept, and they gave me some ideas where to look, starting with the switch itself right at the lever. He suspects corrosion because the previous owner was less than diligent about keeping it out of the weather.
Anyone else have any ideas where to look, let me know. The first problem will be finding my meter in the boxes from moving.
