Voltage not reading

[SobrietyskcuS]

I have a 831a and the voltage gauge doesn’t move the load when I plug some on the 220v. If I ll Plug some in on the 110 side it will work but not on the 220 I have a mini split AC that’s 220 the AC works but it doesn’t register on the voltage gauge.

Voltmeter could be bad.
Use a hand held voltmeter and check the AC voltage across the two terminals of the front panel voltmeter to verify.
What setting is the red switch in on the top of the inverter?
Is the sets contactor closing?
Does the contactor light illuminate?

The red switch is set for 220 I took the fuel injectors out today and it runs and then it stall for a few seconds and puffs black smoke and then runs again. When I close the circuit interrupter it will power but when it stalls it turns off the circuit interrupter.

Sounds like the engine is surging due to a bad governor controller. It's a very common problem with the 831's. Both of the 831's I purchased had bad Governor controllers.
I sell replacement controllers. They are listed in the Parts for Sale section of the Classifieds on the forum.
