- Disconnect electrical connector at throttle switch. Zero ohmmeter and connect ohmmeter leads to both terminals on switch. With throttle valve closed, ohmmeter reading should register infinity reading. Slowly open throttle valve. Just before reaching stop, ohmmeter reading should register 0 ohms.
- If switch does not respond as outlined in step 1, fully depress accelerator pedal and hold in position. Loosen throttle switch and move switch until ohmmeter reading changes from infinity reading to 0 ohms and tighten switch. Roller of switch should be centered on curved arm of throttle lever. If switch cannot be adjusted as described, replace throttle switch.
