Functional check
1. Disconnect the negative cable from the battery.
2. Disunite an electric socket of the gauge switch of permission to start.
3. Check for continuity between the connector terminals at different positions of the selector lever (see accompanying illustration).
4. If there is no continuity on all tests, disconnect the selector rod from the lever and repeat the procedure.
5. If check gives positive result, adjust draft of the selector.
6. If the test results are negative, remove the start enable switch from the transmission and repeat the test again.
7. If this time everything is in order, install the sensor-switch in place and adjust it as described later in this Section.
8. If there is still no continuity in all cases, replace the start enable switch.
Removing
1. Disconnect the negative cable from the battery.
2. Disconnect the electrical connector for the start enable switch (the appearance of the sensor-switch is shown in the accompanying illustration).
3. Translate the transmission to position I, give the fixing bolts and remove the start enable switch from the transmission.
Installation
Installation is in the reverse order.
1. Monitor the quality of the electrical contact of the connector terminals and the reliability of the fastening of the latter.
2. Adjust the sensor-switch.
Adjustment
1. Loosen the selector rod locknut and disconnect the selector rod from the selector rod.
2. Move the selector rod to position "N".
3. Loosen the mounting bolts of the start enable sensor-switch.
4. Insert a ø 4 mm rod into the hole in the selector rod.
5. Adjust the position of the sensor-switch so that the rod gets into the hole in it. Hold the rod as perpendicular to the switch as possible.
6. Tighten the sensor-switch mounting bolts.
7. Connect the selector rod to the stem, tighten the locknut and adjust the rod as described below.
