Throttle Switch
- To test throttle switch circuitry, connect voltmeter across terminals "1" and "2". See Fig 1. With ignition on and engine stopped, voltmeter reading at idle should be 2-8 volts. Above idle position, voltmeter reading should be 0 volts. If throttle switch does not respond as outlined, test switch position as follows:
- With voltmeter still connected, ignition on and engine stopped, insert a feeler gauge as shown in Fig 1. Feeler gauge should produce voltages indicated in chart. If not, replace throttle switch and adjust as follows:
- After replacing throttle switch, connect voltmeter and turn ignition on with engine stopped. Insert 0.016" (.40 mm) feeler gauge. Loosen throttle switch retaining screws until reading is indicated on voltmeter. Tighten retaining screws.
