2016 R-179 Slide Totally Dead

OK my last update on this since I finally figure it all out and got everything working.  So there is a large fuse, I am assuming 30-40 amps bolted to the floor of the RV behind the fuse panel by the door.  So when the positive line on my controller broke off and shorted to the ground it damaged this fuse but did not burn it.  I bought a controller (used) and it turned out to have problems (my luck, returned), my own controller turned out not to be burned, the code 2 it was giving me was not making sense since it was not moving from motor to motor when I was switching connectors.  Any way I put my controller in the system and powered it with an independent battery locally and everything worked.  The large wire from this fuse the controller is very thick (6 gauge or so)  and obviously was not damaged so this fuse is not totally burned but is not allowing enough power to go to the controller.  I disconnected wire from this fuse and used a 30 amp fuse on an empty spot on the regular fuse panel and wired everything and it works great.  25A blows when the slide gets to the end or all the way in since the motors are pulling more than 25 amp when limited, 30 amp fuse is working fine.  At some point I might grab another large fuse and wire things the way they were but for now using regular fuse spot in number 8 which was empty is working fine.  The board should be able to handle the 27 amps or so which is getting pulled by the motors when limited.  I also made a relay system using two relays which would allow me to do without the controller all together for but now things are back to normal, I am keeping the relay system and the wire system which I made for going straight to the motors for emergency use.  All done, hope all of this helps.  To get to the fuse for the slide you have take out the whole fuse box assembly.
