Jerry & Linda,
Welcome to FRF.
Glad to have you with us.
On the fuse problem, disconnect all electrical items in that circuit(bathroom vent fan, monitor and slide-out lights
). Install a new fuse. Operate the slide, in and out, a few time to see if the fuse will blow. If it blows, you'll need to look for a bad wire(shorting to ground/frame
If all is okay, use the process of elimination. Re-connect each item, one at a time to find out which one is causing the fuse to blow.
Enjoy the forums and
