Just purchased first Travel Trailer (05 Forest River Surveyor S223T). Dealer recommended an ems-hw30c, I just didn't want to pay $200 for them to install figured it was easy.
My main 30amp power plugs in on Back Side of Trailer. the only wiring I can find is behind the fuse panel/under sink. Coming up from the floor are a Red/Black/Ground wire, Pictures show where wires go to.
I thought all I had to do was remove Red/Black from Fuse Panel Circuit Board, put those into input of ems-hw30c and then go out of that back to those same Pos/Neg on Circuit board, right? can someone please help.
I installed the way I thought was correct and had no display on remote display and no power to Trailer. I reversed wires and still had no display and no power. removed ems-hw30c and had power to trailer again.
also where can I get an owners or service manual for this. checked the forest river website but could just find 2015 not 2005.
