tachometer not working
Written by rudyg1937 on 10/10/2010 at 04:11 pm

I have never had the problem with the tachometer but I know I have seen similar
problems on other bikes. I would check and clean the terminal on the right rear
ignition coil where the tach takes it's impulse from. Looking at the wiring
diagram it appears both the tach and the fuel cutoff take their signal from the
same yellow with blue stripe wire. I would also pay attention to the connection
to the wiring harness plug for the same wire.

Purely a guess and the first place I would check.

Can someone help me check the tach with what meter and how, and does it hurt to
operate bike with out tach. Probably stupid question, but I had to ask. Thanks

Hi everyone. Noticed today, for some reason, my tachometer quit working.The previous owner changed the instrument gauge set 3 years ago(speedometer,odometer and tach) Looks like I may have a recurring problem. The bike ran fine though. Can so

        Next time it doesn't work try tapping the gauge glass. I always attributed it to the needle sticking at the bottom and once loose never seems to have a problem. It seems to happen more when it is colder out. Last time I had the gauges
