If the engine does not start when the ignition key is turned, the wiring or the switch itself may be faulty. You can do the following check:
- brake the car with a parking brake;
- turn the ignition key to position «start» and at the same time shift gears with the gearbox selector;
- if the engine does not start, use a piece of wire to make a jumper from the positive terminal of the battery directly, bypassing the switch, to the connector «50». The starter should start working.
Attention! During this operation, be sure to set the gearbox selector lever to position N or P, brake the vehicle with the parking brake so that it does not start moving when the engine is started.
