MEP-831A Does not produce 240 volts?

[ECS]

I just got a MEP-831A with less than 15 hours on it.

When I run and test from L1 to N it has 120 volts, and from L2 to N has 120 volts, but from L1 to L2 it should have 240 but it's zero volts.

I am thinking some wire must have been hooked up wrong, but I'm not sure where would be the most likely place/area to look?

Is the toggle switch on the top of the inverter set to 240?

Do NOT change the setting with the set running!

Thanks, I'll open that door and double check and switch it back on forth. Hopefully it is the reason. The meter is reading 120 volts on this one, there is other one running 240 correctly and it shows 240 volts on the meter.

If the meter reads 120 then the switch is in the wrong position.

If you haven't already you ought to download a copy of TM 9-6115-639-13&P.
It covers that and everything else about running the 831A.
