1952 Cub with 12V conversion - may need help

Postby Moondoggie » Wed May 20, 2015 4:56 pm

Just swapped my 1992 Ranger (project truck) for another Cub. It runs and has a belly mower, good tires, etc. Got home and discovered its a 1952 just like the one I already have (6V) but some one installed a Chevy (?, that's what I was told) alternator and converted to a 12V battery. What I see so far is that there's 3 wires coming out of the alternator, 1 black and smaller and 2 large ones wired together going nowhere. The black wire heads to the ammeter(?, I think) and has a diode in series in it. (haven't tried to read the color code yet). Also has a "resistor" bolted to outside of hood and 2 wires to each side of it. I guess I need to make a wiring diagram and try to figure out what's going on. I will definitely be back here later. "CUB FEVER" is a terrible thing to have when there's so many other things "wifey" wants done.

I think this will answer your questions, including the reason for the resister bolted to the hood.

Thanks. The schematic wiring diagram sheds some light on what I see on my Cub. However, it notes that a diode can be substituted for the warning light. And the diode goes to #1 on the alternator. Still not sure where the diode wire goes on mine but it's definitely not to #1. On my Cub #1 and #2 are wired together and go nowhere. Suggestions.
