Spec A Battery Charge Mode
With the genset running, AC voltage is produced in the B1-B2 windings for the battery charge circuit.
• The AC output voltage from the B1-B2 winding is converted to DC voltage when it passes through the full-wave
rectifier bridge (CR1). The voltage is then supplied through battery charge resistor (R1). The 12-volt DC output
(one-ampere maximum) is used to power the control assembly (A1), fuel pump (E2), the remote control, and to
prevent discharge of the genset starting battery during genset operation. This output is not sufficient to charge
a low or dead battery.
