Jayco Greyhawk correct coach battery hook up
Really needed this photo a few days ago so thought I would post it to help the group, and the next desperate guy like me. The Greyhawk is a class C motor-home, mine has a single deep cycle coach battery. The red clip in the picture is a voltmeter, not part of the RV. To make it simple, all the cables (3) with multiple wires are positive, the singe wire cable is negative. The new deep cycle battery had posts of different sizes and one of the positive cable clips did not fit on the positive post, so we had to drill the hole out a little....which is what caused me all my confusion. Hope this helps.
