I'm currently trouble shooting the Onan 7.5kw gen on our AN/TSC185 V 2.
Fault: When battery is connected gen starts automatic
Actions taken: checked start button, starter, wiring harness, Grounds.
Finding: wire F1 From inverter to starter pos + post, grounds out when It is plugged into inverter.
Could the inverter be Unser? any suggestions is greatly appreciated.
