Tach Not working

Hello,

so I recently bought this bike about 2 months ago and have been trying to get the tach to work. The speedometer works fine. When the bike is running the tach needle elevates a little but never works. Any wires to check or anything on the gauge I could look at?

my tach isnt working on my 87 vfr 700 but, like yours, all the other gauges work. im trying to figure out how to get mine working too.

Check the electrical system -
If you refer to my post you'll see how I'm troubleshooting -

in part -

1. Coils packs
2. ECU ( or spark boxes )
3. Pulse generators - trying next

good luck

The tach operates off the coil and spark unit for cylinders 1 & 3, yellow wire, check the connectors.

When I undressed my VFR I also forgot to connect the yellow wire when assembling the fairings back since all the other connectors were behind the instrumental panel except the yellow one for the tach. You very easily forget that...
