Continuity and Voltage Test





1. Disconnect the battery negative terminal.
2. Connect one lead of a self powered test lamp or ohmmeter to one end of the part of the circuit you wish to test. If you are using an ohmmeter, hold the leads together and adjust the ohmmeter to read zero Ohms.
3. Connect the other lead to the other end.
4. If the self-powered test lamp glows, there is continuity. If you are using an ohmmeter, low or zero resistance means good continuity.
