Haven't had this motor long. Hard starting , won't idle right. Think I found problem, charging coil melted to. Think a overheat problem cause head gasket replaced before I bought it.
I'd say something is improperly wired, somewhere, or wires shorted together somewhere. I have no idea where or how. But I will say that there normally would be no connection between the sensor and battery (or battery charger).
Think for I bought it, had a overheat problem. A new head gasket was put on before I got it. It has been hard to start and won't idle. The charging coil melted too
