Full Throttle Switch
- Connect voltmeter between terminal No. 3 of throttle switch and ground. See Figure . Turn ignition on. Voltmeter should indicate battery voltage. Turn ignition off. Disconnect full throttle switch connector. Connect ohmmeter across full throttle switch terminal No. 3 and ground.
- Fasten pointer for Protractor (3084) to adjuster of accelerator cable. See Fig 1 . Screw protractor onto throttle shaft and unscrew throttle shaft nut (if necessary). Push throttle lever to full open (at stop limit). Zero pointer plus disc.
- Close throttle to 30 degrees, and then slowly move toward full throttle position until full throttle switch engages (zero ohms indicated). Protractor should show 6-14 degrees before contacting full throttle limit stop.
- If protractor reading is not as specified, adjust or replace full throttle switch. If protractor reading is as specified, remove FICU harness connector. Turn ignition off.NOTE: ICU terminal numbers are imprinted on connector.
- Using ohmmeter, measure resistance between throttle switch terminal No. 1 and ICU terminal No. 7 and between throttle switch terminal No. 3 and ICU terminal No. 9. See Figure . Readings should be less than .2 ohm.
- Using ohmmeter, measure resistance between throttle switch terminal No. 1 and FICU terminal No. 28 and between throttle switch terminal No. 3 and FICU terminal No. 31. See Figure and Figure . Readings should be less than .2 ohm. If readings are not as specified, repair open or short circuit.
