2004 Yamaha G22 G-MAX (48V - DC MOTOR) Service and Repair Manual

G22EZ is the code carried by the 2004 G22 G-MAX electric car, and LIT-19616-22-04 is the factory manual written for it.

Yamaha built one service volume for the 2003 through 2007 G22 and G23 range, fifteen variants in all, covering gas and 48-volt electric cars and the UMAX Medium Duty utility models. The result is a book that follows the platform through its changes instead of freezing one year.

Work on these cars usually starts electrical. The manual gives the troubleshooting order for the controller, solenoid, forward and reverse switch, throttle input and motor, with the readings to expect at each point, plus full wiring diagrams. From there it moves through the drive unit, rear axle and brake system, with disassembly steps and the wear limits that decide whether a part goes back in.

Steering, front suspension, wheels, frame and body sections round it out, along with the periodic maintenance table the factory intended these cars to be kept on.
