Yamaha G19 controller
 |
The Yamaha G19 is a 48‑V, 300‑A solid‑state speed controller used in electric golf carts, typically driving the main motor and throttle circuitry. Common failures include internal MOSFET or relay burnout from overheat or voltage spikes, capacitor degradation causing erratic throttle response, and wiring harness corrosion leading to intermittent power loss. First‑check diagnostics: verify 48‑V supply continuity at the controller terminals, inspect for visible burn marks or swollen capacitors, and test the throttle input/output with a multimeter while monitoring current draw for abnormal peaks.[oss-gpt-20b] |
