Tractor: 47 AV with magneto, 6v generator. Problem: With tractor running, charging voltage drops as you increase rpm. Battery is at 6.3 volts before starting, then after starting voltage drops to 5.85 or so, then continues downward as you increase rpm, 5.81, 5.79, 5.75 and so on. Back to idle it goes to 5.85. Ammeter is pegged to the discharge side. Stuff I"ve done: Gone all through generator, with field grounded it puts out 9+ volts and increases to 18+ at rpm. So it seems generator is fine. New regulator, all new wiring, new ammeter. All generator and regulator mounts were ground down to bare metal to insure a good ground, test meter shows ground is good. Generator has been polarized more times than I can count. Jumper from BAT to A terminal on generator with fan belt off. Generator rotates a tiny bit clockwize. Will not polarize by jumping to the GEN post on regulator? I have tried more things, but I"ve gone on too long as it is. Hopefully someone has been down this road.
