How old is this cub. My H has the original voltage regulator, I think it's actually a cut out. The older Farmall's had a system incorporated into the light switch witch increased the charging rate when the switch was turned to the first notch, I think it grounded the field. My H goes to a whooping 10 amps on high charge. On the low setting the charge is almost not detectable. Volt meters measure the voltage between the system and ground. Amp meters measure current flowing through a wire. When diagnosing a charging system a amp meter placed in the charging circuit will measure charging amps in the circuit, anything above zero indicates a charge is flowing through the system. A volt meter will measure volts in the system. A generator that is charging will have some voltage above the battery voltage. I have had a difficult time finding a voltage regulator that continues to work on my MF 65 the new ones seem to fail about annually, or at least I have to clean the contacts. Not claiming the new regulators are poorly made but they just seem to fail.

Today's Featured Article - A Question for Dads This recent topic from the Tractor Talk discussion board is being highlighted because it is an awesome display of the caliber of individuals that have made this site their own. The young person asking questions received positive feedback and advice from total strangers who "told it like it is" with the care many reserve for their own kids. The advice is timeless... so although it isn't necessarily antique tractor related, it will be prominently displayed in our archives to honor those who have the courage to ask and those who have the courage to respond in an honest, positive manner.
