2006 Yamaha G23-EC "UMAX MEDIUM DUTY I" (48V - DC MOTOR) ...
Electric UMAX cars run a 48-volt DC motor, and the 2006 G23-EC is covered by LIT-19616-G2-30 under the code G23EC.
Yamaha's coverage takes in 2004 to 2009 and nine variants, the carbureted G23 UMAX models included, so a mixed fleet of gas and battery utility cars works from one reference. Differences between the seasons are called out inside the procedures.
On the electrical side you get battery and charger inspection, solenoid and controller diagnosis with expected readings, and motor removal and inspection, all backed by wiring diagrams drawn to the production harness. That order matters on a utility car, where a no-drive complaint can begin at the pack or end at the motor.
Chassis work is covered to factory figures: brake adjustment, rear axle service, steering, front suspension, wheels, frame and body. Give the counter G23EC with the part number when confirming a part.
