Testing For Continuity

Testing For Continuity:

This test checks for continuity within a circuit. When testing for continuity at a connector, you may not have to separate the two halves of the connector. Instead, probe the connector from the back. Always check both sides of the connector because dirt and corrosion between contact surfaces can cause electrical problems.

1. Disconnect the negative cable from the vehicle battery.
2. If you are using an ohmmeter, hold the leads together and adjust the ohmmeter to read zero Ohms.
3. Connect one lead of self-powered test light or ohmmeter to one end of the circuit you wish to test.
4. Connect the other lead to the other end.
5. If the self-powered test light glows, there is continuity. If you are using an ohmmeter, low or no resistance means good continuity.
