Rev counter issue

Today I took off the belt cover to inspect the belt and also had the windscreen and part of the fairing off. After I put everything back together, I started the the scooter and went for a short ride. It was then that I realised that the rev counter needle was not working. I rode back to my garage and when I switched the ignition off, the needle dropped on the other side of the stop. Switching the ignition back on the needle hits the stop because now it cannot go passed zero and remains there until I switch it off again. The pic shows the needle with the ignition off. My problem is that I don't know where the problem was caused, was it by removing the belt cover or the fairing. Does anyone know where the RPM sensor is located? Thanks for any info.

Never heard of a problem like this before, so I'm just guessing here:

I would check for a faulty wire connection at the Meter Panel wire harness plugs. Disconnect the battery then clean the Meter Panel terminals & wire harness terminals.

Some how or other this suggests that the polarity may have been reversed --although I don't know how that could have happened and only effected the tachometer.

There are no wires associated with the belt case that effect the tach, so the problem must have originated when you removed the front cowling and disconnected wiring at that end.

Good luck, and please keep us informed

Maybe its just jumped the stop somehow!

After a mostly sleepless night, I managed to fix the tachometer. This morning I removed the front fairing, inspected all the wiring and everything was in place. I took off the clocks and removed the the front glass (plastic). Now I thought, what am I to do? At this point I did not know if the problem was mechanical or electrical. Upon close inspection I figured that there is no way that the needle went past the stop, the needle is thick plastic and does not bend easily without breaking. So, my next step was to try and pull the needle off and install it where it should be, but it was a bit hard and thought that I might break it. Then I thought what if I moved the needle back one full revolution, although to tell the truth I hesitated it at first because I thought that I'm really going to break it this time then, what the heck, it's knackered anyway and I started turning it around when about half way it just went all by itself the rest of the way and settled on the stop, plugged the connections, started the engine and it worked perfectly .

The only reason I could think off is that I was trying to find a place to install speakers inside the fairing and the speaker magnet may have had something to do with it, whatever it was I'm glad it's fixed now.

Cheap fix - always the best.

Cheers,

Congratulations "yammer"... good use of the powers of deduction... that, and a great "what-the-hell, it's-already-broke" attitude
