Im having issues with my tachometer. It wasn't working the last time I took it out. Yet all other gauges are fine. For a brief moment the tach needle moved while running, but then went dead again. The backlight works and the hour meter lights up, but did not change any after running for more than an hour. To me that sounds like an issue from the motor. I have no idea where the tachometer wires connect to the motor. Hoping someone can point me in the right direction. Thanks!
