Having some trouble with my gauges and could use some help troubleshooting.
The symptoms are identical to if the key was on with the kill switch in the off position. When turning the key on, the gauges complete self test (full sweeps of all instruments), then the temp gauge goes to full-hot. The CHEC is lit with or without the jumper installed. The jumper does not produce any engine codes. No gear position information. All other features work and the bike starts and runs fine.
I have confirmed that the gauges are getting 12V continuous for the clock and also switched 12V (orange/green stripe wire). The ground at the gauges is also good. I have swapped in another set of gauges that showed the same symptoms. Also, I have used another wiring harness with the same results. I have also checked another ECU that does the same thing. I have tried this with a MoTec, a Bazzaz, and removed both and tried just the factory harness and ECU.
I have a 2Ga ground cable going to the engine with the stock ground wire running to the ECU. I've ohmed this out and it looks good. I also ohmed from the battery/chassis ground to the gauge ground and it shows as less than an ohm so the ground looks good.
Last night I ran ground and 12V to both 12V pins on the gauges without any other connections and it shows same results (removing the harness from the equation).
Any suggestions?
