Factory inverter problem

My factory inverter is only coming on in the 400w setting. It's like I did the "only 400w mod" but didn't. I thought maybe it was from tapping into the power outlet fuse for my Switchpros but it's not that. When I push the inverter switch it goes to green/orange then nothing for the next two pushes. Checked at the outlet and it works but only when the switch is in 400w mode. Tried a new switch and does the same thing. Any thoughts what the problem could be?

 

Read your manual. Its covers how to use the outlet

● While the vehicle is being driven The maximum capacity of the power outlet is always 120 V AC/ 100 W.

●The maximum capacity is 120 V AC/400 W when the following conditions applies:
Vehicles with an automatic transmission The shift lever is in P or N.
Vehicles with a manual transmission The shift lever is in N and the clutch pedal is not depressed. The maximum capacity of 400 W can only be restored by turning the power outlet main switch off and then on again under condition described above

 

Yeah, started there first w/manual. For some reason the inverter was 400w whether driving or parked and the switch indicated the same. After checking further I decided to disconnect my dual battery and reconnect it and the problem went away??? No idea what that would do but for now it works like it should. I'll just roll with it and see if it happens again.
