Testing For Continuity

Continuity Check Through A Switch

1.  Remove the fuse to the circuit involved.
2.  Connect one lead of a self-powered test light or ohmmeter to one end of the part of the circuit you wish to test.
3. Connect the other lead to the other end of the circuit.
4. If the self-powered test light glows, there is continuity. When using an ohmmeter, LO or no resistance means good continuity.
