Thanks. Do you mean the disconnect switch? I wired the new converter directly to the batteries.
First, make sure the red wire through the disconnect switch in that photo is connected to the battery pos post. Also make sure the black wire through that DC breaker is also on the pos battery post (or that they go to a buss which is on the pos post.
That is independent from the wire from the charger to the battery that also goes on the pos post. I can't remember if you put in new batteries and maybe didn't hook up all the wires like it was OEM.
Besides an "open" in the pos path, part of the neg path might be through the frame. Maybe the wire from the battery neg post that goes to the frame is open either at the battery or from a rusty frame connection.
