An ohmmeter is connected to two consumer terminals or to two ends of an electrical wire. It does not matter which wire of the ohmmeter (+) or (-), attached to a particular contact.
The measurement of resistance in the automaker is mainly limited to two areas:
- A) checking the resistance included in the electrical circuit or some other part;
- b) «ringing» electric wire, switch, sensor, electric heating coil. At the same time, it is checked whether any wire is broken and whether this is the cause of the failure of the device connected to it. For measurement, an ohmmeter is attached to both ends of the wire under test. If the resistance is 0 ohms, then the wire is good. With a broken wire, the device shows ∞ Ohm (infinite resistance).
