First, the AC outlets have nothing to do with the battery and the breakers are for 110v AC only.
The fuses are for the 12v DC side only.
Most common cause of your issue, is reversing the battery wires when reinstalling the battery.
This eithe blows the fuse right by the battery or trips the resettable fuse that TURBS mentioned.
It's nearly always tucked up along the A frame and gets overlooked many times.
