1998 Yamaha G19-ES "ULTIMA" (48V - DC MOTOR) Service and Repair Manual

For a 1998 G19-ES, the code on the plate is G19ES and the manual Yamaha published is LIT-19616-G1-90.

Coverage runs 1996 to 2002, with the G19-EP, G19-ER, G19-ET, G19-EU, G19-EW and G19-AX all described in the same volume. Yamaha saw no reason to split the 48-volt series into separate books, and for an owner that means one reference rather than a shelf of them.

• Motor and controller diagnosis with factory test points
• Charging system procedures
• Wiring diagrams for the 48-volt circuits
• Brakes, steering and suspension with torque specifications
• Service limits for inspected components

Because this is dealer material, the figures quoted are the ones Yamaha engineers set rather than values carried over from a generic guide. Match G19ES and the fitment is right.
