Are you sure that you have no power to the system? What make of jacks?
Since this is a manufacturere installed item it will not be in the chassis fuse box. If you have one, look for help int the Allegro manual. You might also contact Allegro as they are well known for helping their customres.
Thanks for the reply. The manual just says there is protection but thats all. Tiffin doesn`t respond, they might be under water. The manufacturer doesn`t respond either so I thought I might get help here
Tiffin is not underwater. Do you have a wiring diagram? I would start by looking near the batteries. There will also be several different solonids that control the jacks. The coach should be still under warranty. Take it back to the dealer or are you like most of us, not worth the hassle
