What is this?
I'm trying to get a grasp on my electrical system. I have both engine and chassis and body manual but I'm still a little lost on the electric distribution in my truck.
This green box has six terminals on it. A1, A2, B1, and B2 are for the relay part. X1 and X2 are for the transformer part. My stereo and trailer lights were hooked up to the A1 and A2 relay terminals. There is a 24v Hella relay attached to the X1 and X2 terminals (transformer terminals). From the relay one wire goes to the 12v white lead off the solar converter. THe other wire goes to the Positive end of my 12v battery.
Am I wrong in assuming that that green box changes 24v down to 12? It seems like that green relay/transformer box is not essential in my setup.
I have seen an great writeup on Stone's solar converter setup and I think I'm going to mimic.
I've been having issues with my batter draining and I would like to clean up some of the wiring in the truck.
Any help would be greatly appreciated!
