Switch check on a current transmission

The majority of consumers of the electric power join and switched off by the switches put in action by a hand. Also there are the switches put in action automatically. The sensor of pressure of oil and the sensor of level of brake liquid belong to these switches, for example. Main objective of the switch short circuit and disconnection of that contour. There are the switches disconnecting a contour of weight, and the switches disconnecting a plusovy contour.

Check of switches of lamps and electromotors

 PERFORMANCE ORDER

  1. To remove the corresponding switch.
  2. Simple switches have only 2 contacts for cables. In this case on one contact tension (+), and after inclusion and on other contact too always should move. Also there are switches with several contacts. For these switches to determine by the scheme, tension should be put to what plug, if necessary previously to include ignition.
  3. To check the indicator, whether tension is put to the switch. If the lamp of the indicator burns, to turn on the switch and to check, whether there is a tension on the target plug. If tension is, means, the switch is serviceable.
  4. If on the entrance plug tension is absent, in conducting there is a break. Wires should be checked according to the scheme, if necessary to lay a new wire.

Check of switches sensors

The sensor of pressure of oil, sensors of level of brake and cooling liquid belong to switches sensors, for example.

 PERFORMANCE ORDER

  1. To connect the indicator or an ohmmeter to entrance and target wires of the sensor, for this purpose to disconnect cables on the switch.

The switches which have been screwed in in the block of cylinders, as a rule, of the plug of weight have no, as as a pole of weight the switch case serves.

  1. At the closed switch the indicator should show current course. Best of all the ohmmeter is suitable for check: At the closed switch it should show 0 Ohm, at the opened sensor infinity Ohm.
  2. Serviceability of sensors of level of cooling and brake liquid most quicker can be checked, having disconnected at the included ignition a wire from the sensor, to close it on weight, for example, on the block of cylinders. If the alarm lamp on a guard of devices lights up, malfunction is concluded in the sensor.
  3. Special case — the sensor of pressure of oil: On the idle engine contact will close (an alarm lamp burns), the sensor is disconnected at a certain pressure of oil.
