Oliver OC-3 Chargung System???

So did the OC-3 ever have a charging system? I can't see where there ever was one on mine. It has a Wico mag for spark, a battery and electric starter, but no generator or alternator and no evidence of ever having one.

Generator sits within a big clamp at front left of engine right above the drain plug on the water pump to rad pipe, if that makes sense.
Originally it was a 6v system. A regulator would sit above generator attached to the block.
I find my 6v system sluggish to start, and often boost it for a short 200A 12v burst with my battery charger to get her up and running. NOT good for the battery though.
Your starter must be 12v, which is not original.
On www.cletrac.org there is a thread showing a great 12v alternator conversion for OC46s using an Isizu unit. I think it is identical for an OC3. Some quite easy modifications to make a bracket, and it all lines up with the belts nicely. Quite a few folks have converted their units from 6 to 12v, and I know why!

Oh I see. You mentioned a 12v battery in your earlier message.
Mine is an engine in need of new fluids and some TLC. Maybe this is enough to drag the moving parts so I cannot start ii easy with the 6v battery.
Or maybe it is like Tramway says, we both need bigger cables. The cables on my 12v 550 tractor are a lot heavier than those that came with my OC3. I will try that idea myself I think....before I go the 12v upgrade route.
 

Yes, when I got it , it had a 12v battery mounted in a box on the loader, but it was strictly just used for starting and it has no charging system.

All of the starting cabling was junk, and I am in the midst of replacing it all. In the meantime, I was trying to jump it straight from the battery with the cables as I had done before, and it barely will crank it over.
