Title: Wiring for rev counter
Post by: Sharky on January 28, 2019, 07:19:40 AM

The rev counter on my bike wasn’t working when I bought it, and with looking inside Speedo housing I found the rev counter wiring disconnected. Any idea which wire goes where to the spade connectors?

Hello,
I've found on an old French service bulletin the wiring of the electronic tacho to replace the mechanical one.
The tacho has 3 wires : Red is +12 V Brown is ground and green is impulse from the ignition.
With a multi-meter you should be able to find where are the first two going and, then, find the place for the third...
Hope this helps.
