12 V going to the pump, but is it turning (do you hear it running). If not change it.

You have voltage,but not Amps.Voltage plus Amps = Power

I don't understand your question. Are you asking if 147 VOLTS is too much at the receptacle? If so, yes - that's too much. Are you asking if 147 amps is too much to expect from your generator? If so, yes, that's far too much.

There are many possible reasons from stator output voltage to sensing, to fuel to control boards. A good place to start (as the unit does run) would be with the fuel system, if it has sat a long time it won't help. Also the fuel filter. try conencting to an external fuel tank versus the vehicles, as sometimes pick up tubes in main tanks can be an issue. Also check the correct oil level and viscosity / and oil pressure switch. Failing that I recommend a service center, as there really are so many causes, I cannot list all on here.

This generator has a built in transfer switch. If you do not have an external source of 240 volts going in to the unit (utility power), the transfer switch will show a fault or "abnormal" reading. If you do have utility power going in to the transfer switch, and the generator is on then you have a faulty transfer switch. It is time to warranty or get a replacement switch.
