Part number LIT-11616-05-90 covers the 1986 G3-E Sun Classic, the 36-volt DC-motor car carrying code G3 - E.
Only two seasons sit inside, 1986 and 1987, together with the alternate spellings Yamaha used for the model in its literature. That makes fitment straightforward: confirm the code and the part number and there is nothing else to check.
What the manual gives you is the factory's method. Electrical diagnosis follows a stated order with the wiring diagram to hand rather than trial substitution of parts. Mechanical sections give disassembly sequence, inspection measurement, service limit and torque, in that order, for the brakes, steering, suspension and axle. On a car this old that discipline is what keeps a repair from turning into a second repair.
