2003 Yamaha G22-EY "G-MAX" (48V - DC MOTOR) Service and R...
Unlike most of the G22 listings, the manual for the 2003 G22-EY is tied to that model year alone. The part number is LIT-19616-22-03 and the car's code is G22EY, a 48-volt DC motor machine.
A first-year book has a certain clarity. The specifications in it describe the car as built in 2003, without later qualifications, which helps when you are trying to work out whether a component on your car is original.
Content follows the factory pattern: identification and specifications, periodic maintenance, the battery and charging system, solenoid and controller diagnosis, motor service, drive unit and rear axle, brakes, steering, front suspension, wheels, frame, body and complete wiring diagrams.
Quote G22EY with the part number when checking fitment. Early G-MAX cars share a great deal with the later ones, but not everything, and the code is how the difference gets resolved.
