8.5. Check of work and replacement of the switch of coupling (where it is provided)

The switch of coupling located in the top part of a pedal of coupling, prevents engine start at not squeezed out pedal. The switch being a part of a chain of a starter, in normal situation will open. When squeeze out a coupling pedal, it presses on a small pusher in the switch, closes a chain and includes a starter.

If the engine of the car is started without pressing a coupling pedal, it means that the switch either is faulty, or is incorrectly adjusted. To check its work, disconnect the electric socket and connect an ohmmeter to socket plugs. The chain should be not closed at the released pedal (a pedal above) and is closed at the squeezed-out pedal. If the switch does not work thus, try to adjust it. If it is not possible, replace it.
