Check of gauges

Gauges concern, in particular: the gauge of the relay of pressure of oil, the gauge of a reserve of a brake and cooling liquid.

 CHECK

1. Attach a control lamp or an ohmmeter to switch plugs. For this purpose disconnect cables from the switch.

The switches screwed in the block of cylinders, as a rule, have no weight cable as connection with weight is carried out through the case.

2. At the closed switch the device should give evidences. Is better to use for this purpose an ohmmeter. At the closed switch the ohmmeter should show a zero the Ohm at opened infinity the Ohm.
3. Working capacity of gauges of a reserve of a cooling liquid and a brake liquid is the most easier for checking up as follows. At the included ignition disconnect from the switch a wire and put it to a reliable point of weight, for example to the block of cylinders. If the corresponding signalling device on the panel of devices, malfunction in the switch lights up.
4. The special case represents the gauge of the relay of pressure of oil. At the idle engine contact is closed (a signalling device burns). The switch works only at certain pressure of oil.
