Yesterday i looked down at my speedo as i was putting along in 40 mph traffic to see that Mr Smith thought I was going 130 mph.
The speedo was swinging wildly beyond my real speed, whether i was going 20 mph or 60.
The cable is fine. And i think the drive is fine too.
I disconnected the cable from the drive, checked that it was in the speedo firmly and turned it by hand at the drive end - the speedo showed 50 Mph. I put my drill on the cable - same crazy result (yes with the drill in reverse).
I took the speedo off, went over to the bench, and turned it manually with an allen key. Again, spinning the allen key between my fingers shows up at 20 to 50 mph per Mr Smith.
However, if it do the same thing with the speedo and the allen key but hold the speedo upside down, the needle barely moves. Turn it right side up - problem is back.
Should i mount it upside down on the bike and put a mirror under it to see my speed that way? Or does someone have a theory or suggestion for speedo repair.
Note: it is the Smiths SSM 4003/00 1000 model, with the NVT logo.
Google helped me find a speedo repair shop here in San Diego, Foreign Speedo, plus there are lots of others.
Suggestions?
