1998 Yamaha G16-ES "ULTIMA" (36V - DC MOTOR) Service and ...
Anyone servicing a 1998 electric ULTIMA is working on a G16-ES, code G16ES, with a 36-volt DC motor. The factory manual is LIT-19616-G1-60.
It is a platform book rather than a year book. Coverage takes in 1996 through 2002, the electric cars G16-EP, G16-ER, G16-ET, G16-EU, G16-EW and G16-EX, and all seven carburetted G16 variants from the G16-AP to the G16-AX. One part number, thirteen companion models.
The material is written as instructions, not description. Each repair has its sequence, each measurement its limit, each fastener its torque. Wiring diagrams show the harness as built, and the diagnostic sections are indexed by what the car is doing rather than by component, which is how a fault usually presents itself.
Before ordering, read the code plate and confirm G16ES.
