Welding
1. The engine starting system switch is located near the rotating end of the clutch pedal. The switch can have one of two types of connector: three-pin or five-pin. When the ignition key is turned to the Start position and the clutch pedal is pressed, the starter circuit is closed and the starter begins to operate.
2. If the starter does not engage when the clutch pedal is pressed, adjust the switch (see item 9) and repeat the check. If the starter still does not engage, check the switch (see step 4) and, if necessary, replace it (see step 7). If the starter engages when the clutch pedal is released, adjust the switch and recheck its operation.
3. If the starter does not engage when the clutch pedal is pressed, this indicates either that there is no voltage supply to the switch, or that its contacts are not closing.
4. Using a voltmeter or test light, check for voltage at the switch (see wiring diagram at the endchapter 12). Voltage should be present when the ignition is turned on (the engine is not running). If there is no power supply, repair the open or short circuit in the wiring between the ignition switch and the switch.
5. Check the switch for proper operation. To do this, press the clutch pedal and make sure that the resistance between terminals 1 and 2 is zero. Once the clutch pedal is released, the resistance should become infinite (figure 9.5). Adjust the switch (see item 9).
Replacement
6. Disconnect the electrical wiring connector.
7. There are two types of switches installed on cars.
- a) If the switch is installed at the front, turn it 90° and remove it from the bracket.
- b) If the switch is installed on the side, unscrew the two mounting screws and remove the switch from the bracket.
8. Installation is carried out in the reverse order of removal.
Adjustment
Note: Front mounted switches are not adjustable. Check the clutch pedal height (see paragraph 8).
9. Loosen the fastening nuts and move the switch so that when the clutch pedal is pressed it is closed. After completing the adjustment, tighten the switch mounting nuts.
