I have a Bobcat that I purchased new from ATC in 2011. I had them install the wiring for a future solar install, which consisted of a single copper wire. I had often wondered what I was going to do with the negative wire. I recently purchased a 100 watt panel and Wanderer controller from Renogy.
I'm still trying to figure how I can get it to work with the one ATC installed wire. I guess that's not true. If I connect the positive wire from the panel to the ATC copper wire on the roof, then attach this ATC wire to the controller, then attach the negative wire from the panel to the controller, it works fine.
However, what I want to do (as ATC has suggested and what has worked for them in the past), is not to connect the negative wire on the panel to anything, but rather run a copper wire from the negative port on the controller to a ground on the camper, leaving the positive as described above, and ground the panel to the roof. This has not worked for me.
I would really like to take the ATC approach, as I don't want to have to snake the negative wire from the panel on the roof to the controller inside the camper.
Renogy has said in need to run both wires from the panel to the controller to get it to work.
Any suggestions? Thanks.
