Hey 49 - Ammeter should show a small charge (a couple amps) on low charge with the motor at governed speed. The discharge indication you are getting is puzzling. You sure the ammeter is working correctly? Check by sticking a voltmeter across the battery terminals with the motor running at speed. A reading of 13.5 volts or higher says the battery is being charged. It's normal for the field resistor to get warm in operation. However it will run pretty hot if you are using the old (6 volt) resistor on 12 volts. (On 12 volts it must dissipate 4x the heat it was originally designed for...) Changing over to a regulator is straightforward. It gets wired same as the cutout except for the wire from the "F" terminal on the generator. That wire gets relocated from the light switch to the "F" (or "FLD") terminal on the regulator. (The BAT and GEN wires get connected to the regulator same as for the cutout.) Make sure the regulator is solidly grounded! Running an auxiliary ground wire from the regulator base to a solid ground on the engine or frame is good practice. Also the regulator will last longer if it's physically mounted where it is away from vibration/heat - NOT on the generator if at all possible!!
