I bought a re-built generator from a tractor supply with a new regulator. You would think it would be a no brainer and expect problem resolved.
I had a new bat on the tractor. I had re-wired my charging circuit. It was simple and correct. No charge. I took the gen/reg to an old timers Starter/Gen/Alt repair shop. He went thru and cleaned up the gen commutator and adjusted the brushes. He adjusted the regulator to the gen on his tester. He ran it under load for 20 minutes. Final output was 7.5V and 20 amps on his tester. The thing I liked was I now knew I had a good unit. Charge was $20. I bolted it on and problem resolved. Another suggestion might be to re-wire your chgarging circuit with new wire and soldered connectors. If you still have the old wiring and connectors you may not have a good solid circuit. Old wiring may wring out as OK for volts and ohms on any single wire and yet fail to carry the current properly under load. I agree you may have damaged the reg with wiring reversed. Your bat should be replaced with a known good bat or a new bat. If you take your unit to a shop you can hold on bat replacement. If the shop tested unit doesn't work it's your wiring or bat.
