Looking at my fuse

[Allen in MT]

On my 2005 Monty 3400RL and the slide stoppage issue I'm looking back onb the wall behind the battery box and lippert pump for a fuse. There are 2 on the back wall and I'm assuming the 50amp is the one with red and black wire on them that need to be replaced with the 80 amp. The other has 4 wires comming off it. Both are covered with a red plastic type cover. The slides stop 4-5 times when going out and comming in. Batteryies are fairle new but will check them out.

I didn't take a chance and replaced both with 80 amp auto-reset breakers. Have not had a problem with slides nor level-up since.

They are actually auto reset circuit breakers. I replaced the one to my pump with two 40 amp breakers in parallel several years ago as I could find those locally.

It was the one to the pump that Keystone replaced with an 80amp.

On our previous fifth wheel I had to replace the factory fuse with an 80 amp for that exact reason. The slides were stopping and starting up until then and after the 80 went in that problem never came back but lots of other problems came along, I could write a book
