Lifting the legs too far will cause the fuse to blow. I don't understand how the 50 amp re settable circuit breaker would trip running the legs. The 30 amp fuse should go first. I haven't seen a 2007 era wiring for a while. I am guessing the left CB is the one with the orange wire and fuse to the leg motor? Is there a picture from a little further out that show more of the wiring?



You say the legs work smoothly. Is that under load? If they are smooth running then I would look at the drive motor.
