E-Z-GO Voltage RegulatorPart number 27739-G01, E-Z-GO gas & electric carts starter / generator system part The voltage regulator 27739-G01 (27739G01) helps limit and regulate the power being sent to the batteries in charging process, availabled for many E-Z-GO gas and electric cart models, including:
 About starter / generator system: Starter / generator starting system allows a starter to be switched to a generator. This saves weight and space of engine. The starter / generator is engaged with the engine shaft through the necessary drive gears. As an important part of starter / generator system, the voltage regulator will ensure that there is a steady flow of power, which eventually also plays a major role in keeping the electrical functions of the cart running properly. Wiring Diagram (only for reference, need to be adjusted for each individual application):  When the solenoid is energized through the logic switches (key switch and throttle switch), current flows from power positive (B+) through the solenoid, to F2 terminal of the starter / generator, though the field winding to F1 terminal, then to A2 terminal, through the armature to A1 terminal to ground (B-). That completes the circuit, so the starter / generator begins to spin. As it spins, a voltage appears at the DF terminal of the starter / generator, which is connected to the voltage regulator. The voltage regulator’s job is to internally connect this voltage from DF to ground (B-). As DF goes to ground (B-), the voltage at F2 increases as a path for the charge winding inside of the starter / generator is completed. The charging current to the batteries is proportional to the speed of the motor and the charge state of the batteries. It is constantly completing the current path from DF to B- as required to provide this charging current. How to test: In order to test the function of the starter / generator and the voltage regulator, the wire attached to DF can be removed and while a meter is used to monitor the voltage B+, DF can be shorted to ground (with a jumper) with the motor running. Before the jumper is shorted to ground, the voltage at B+ should, of course, reflect the charge state of the battery (around 12 volts), but when the jumper is touched to ground (which is what the Voltage Regulator does in instantaneous bursts), the voltage at B+ should rise as the motor’s speed is increased. It should peak at about 15 volts (the maximum output of the starter / generator’s charge ability). If it does increase, then the starter / generator is alright. If it doesn’t, there is a problem with the starter / generator. If the voltage does increase, but the voltage at B+ doesn’t increase when the wire is re-attached to DF as the speed of the motor is increased, the voltage regulator is possibly damaged. |
