1984 Yamaha G1-EM4 (36V - DC MOTOR) Service and Repair Manual

A 1984 electric G1-EM4 is documented in Yamaha manual LIT-11616-G1-83 under model code G1-EM4.

Thirteen variants share the volume across the 1982 to 1989 model years. Yamaha kept one book current for the late G1 range, and it separates the electric and carbureted drivetrains while treating the chassis as common ground.

• Motor, control circuit and charging system tests with specified readings
• Complete factory wiring diagram
• Rear axle and brake service with wear limits
• Steering and front suspension procedures
• Torque tables and periodic maintenance intervals

Written for the bench, not the showroom. The steps run in the order the work happens and the numbers are the factory's, which is what keeps an aged 36-volt car serviceable rather than experimental.
