2006 Yamaha G22-EC "G-MAX" (48V - DC MOTOR) Service and R...
A 2006 electric G-MAX
Yamaha's book for the G22-EC is LIT-19616-22-04, and the car's code is G22EC. Both are worth writing down before you start ordering.
Coverage runs 2003 to 2007 over fifteen variants, taking in the carbureted G22 cars and the G23 UMAX Medium Duty utility models alongside the 48-volt electrics. A single reference for the platform, with the year notes kept in the text.
Because the drive system is electric, most troubleshooting begins with the pack, charger and solenoid, then the controller and motor. The manual gives that order and the readings that separate a healthy component from a failing one, with complete wiring diagrams to follow the harness.
Brakes, rear axle, steering, front suspension, wheels and body work are covered with factory torque values and wear limits, and the maintenance table sets the service intervals.
