I hate to bring this subject up again. I have searched all over the forum for an answer with no luck. I have an older coach, 2010 Dutch Aire 4308 with solar prep. I've found a solar prep wire and fuse holder in the basement transfer switch area; however no negative wire. Before I cut a hole under the plate on my roof, I'd like to know if there is one wire or two. I'm assuming there are two with one grounded. Can anyone confirm that or what I will find? BTW, I asked Newmar the same question and they sent me a schematic of the 5 amp chassis charger. Go figure. Thanks, Bob

Solar prep should consist of a red and black 6 AWG wire. Mine were taped together in the basement. Also along side it was an ethernet cable that goes to the panel in the house where the inverter controller and other electronics reside. This is speaking from a 2017 solar prep.
