I am having a little trouble and I was hoping someone could shed a little light on this for me.
I am trying to hook up this hour meter:
It's a 3 wire set up. 1 ground, 1 ignition, 1 electric when engine on.
The thing is, I don't know what to hook up to to get power only while the engine is on. The engine is a Honda V-Twin GX670. Here is the manual for the engine.
Page 18 has the electronics schematics. It has the 20 amp charging system on it. I know where to ground it, I know where the ignition wire is, but I don't know which circuit would have current only while the engine was running.
Any help would be greatly appreciated.
