Posted by ROB MINDRUP on September 29, 2013 at 19:25:26 from (199.36.195.2):

FINISHING A CHARITY PROJECT FOR THE LOCAL KNIGHTS OF COLUMBUS COUNCIL, A 1958 FORD 641 WORKMASTER, 134 GAS, 4 SPEED, 6 VOLT POSITIVE GROUND. NEW BATTERY, REBUILT GENERATOR, NEW B-CIRCUIT VOLTAGE REGULATOR(2X) AND NEW WIRING HARNESS. AFTER POLARIZING GENERATOR EVERYTHING WORKS GREAT UNTIL I BUSHOG FOR ABOUT 15 MINUETS (OPERATING TEMPERATURE) THEN THE GENERATOR LIGHT COMES ON AT IDLE UNTIL RPMS REACH 1500-LIGHT GOES OUT UNTIL RPMS REDUCE TO ABOUT 1100-LIGHT COMES ON (BATTERY NOT RECEIVING CHARGE). WITH A VERY LIGHT "TAP" TO THE SIDE OF THE VOLTAGE REGULATOR THE LIGHT WILL GO OUT AND ALL IS WELL UNTIL I MOW FOR ANOTHER 5 MINUETS THEN LIGHT COMES ON AT IDLE AGAIN. BATTERY IS BEING DISCHARGED AS IT DRAWS 12-13 AMPS ON A CHARGER AFTER MOWING. INSTALLED SECOND VOLTAGE REGULATOR WITH IDENTICAL RESULTS-VOLTAGE REGULATOR IS STICKING. READY TO REDUCE THE SPRING TENSION ON ONE OF THE TWO MAGNETIC COILS-WHICH ONE IS THE QUESTION, THE VOLTAGE REGULATOR COIL OR THE CURRENT REGULATOR COIL? ALSO HOW MUCH TO ADJUST/BEND? THANKS FOR ANY HELP, ROB (MASSEY FERGUSON MF-50 GUY).
