Hi Guys,

Brand new to the forum, so hi all.

My problem is that my rev needle has stopped working on my tach. It does it’s cycle when I start the bike then doesn’t work. Everything else is working. I’ve tested the voltage on the green/green yellow input and I had 11v iirc. Could it be the ECU or the tach itself? Any other things I can do do determine what the problem is?

Thanks

When you unplug the 9p connector from the tech there will be a Yellow/Green wire. Check for continuity from there to the spark unit connector (CDI) which is on on the right side of the tail section. Its the black box behind R/R.

If there is no continuity then your wiring is the problem. If there is then there is a problem with your tech.
