2024 Yamaha UMAX 2 POWERTECH AC Service and Repair Manual
PowerTech AC drive on the 2024 UMAX 2 carries code YUM2E24, and Yamaha covers it in LIT-19616-A3-12 alongside seven other 2024 UMAX configurations.
On an AC car the sections you will live in are the motor and controller chapters: insulation and continuity testing, controller fault diagnosis, battery pack service and charging system checks. Yamaha gives these as tests with expected readings, which keeps troubleshooting from becoming parts replacement.
The chassis chapters are shared with the EFI cars in the same book, covering brakes and parking brake, steering, front and rear suspension, wheels and body panels, with torque figures throughout. Wiring diagrams are reproduced in full.
Confirm YUM2E24 on the vehicle identification plate, and quote LIT-19616-A3-12 when you check that a part listing matches.
