OK, Glen. You have a 6V battery. Now to ensure you want to finish it as OEM with the POSITIVE GROUND set up, first get the right battery cables. The LINK below is for the OEM style Ford Tractor ground strap used from 48-64. It is a HD flat, braided, strap 11" long and is correct for all models from 1948 thru 1964. Many of is use JUST8NS or DENNIS CARPENTER for the correct parts. By your comment the you have RED to positive and BLACK to ground on the battery cables doesn't mean you have the correct 6V set up and possibly means you have the smaller gauge 12V battery cables. 6V requires 00 gauge on the NEG (-)bat post to the starter solenoid, the braided ground strap connects the POS (+)bat terminal to an iron casting or the steel metal frame. BUT, that still doesn't complete the 6V/POS GRN set up. The generator is wired to a 3-wire/2-Brush unit which then connects to a 3-wire tab [ARM BAT FLD] Voltage Regulator. It is imperative that you have the wiring all correct BEFORE you fire up the system. That's where your F0-20 Manual comes in so you can see and identify the schematic and wire it correctly. If you get the ARMATURE BATTERY and FIELD connections mixed up, you will smoke the VR. I will rebuild your carb and exchange it for the correct TSX-706 or 593 carb. My email is open.
