You most likely have high resistance in the wiring to or from the generator.
I attached the wiring diagram and we need to test the resistance or voltage drop each of these wires.
If you test resistance, then you need to remove each wire at both ends and measure ohms from end to end. You should have less then a half ohm on each wire.
If you are going to voltage drop them, then leave everything hooked up and measure voltage of the wire from end to end. This is checking how much voltage is being used by the wire.
Let me know what questions you have but I would start with the the wire on the S terminal as this is the control wire and I suspect is the issue.
