1981 Yamaha G1 (36-VOLT DC MOTOR) Service and Repair Manual

Early electric G1 cars are covered by Yamaha part number LIT-11616-G1-AE, and the 1981 36-volt DC motor car is identified in it as model code G1-E2.

Three model years sit in this volume, 1979 through 1981, along with seven variants: the carbureted G1, G1-A, G1-A1 and G1-A2 and the electric G1-E and G1-E2. For a car this old that breadth is an advantage, since parts and assemblies were carried over and the manual shows which procedures are shared.

The electrical content is the core of it. Motor service, contactor and controller checks, charging circuit tests and the complete wiring diagram appear with the values Yamaha specified. Mechanical chapters handle the rear axle, brakes, steering and front suspension, each with its own service limits and tightening torques, and the maintenance schedule sets out the inspection intervals.
