Theory Of Operation
The purpose of the following procedure is to demonstrate how to check the resistance of a circuit with an ohmmeter.
NOTE:
The circuit shown in illustration is an example, and is intended for demonstrational purpose only.
The following are circuit tests covered in this procedure:
- Testing For An Open Circuit Using An Ohmmeter
NOTE:
Perform the following test using a known good multimeter.
Below is a list of possible causes that could be related to an Open Circuit condition.
| Possible Causes |
|---|
| OPEN CIRCUIT (CHAFED, PIERCED, PINCHED OR BROKEN WIRES) |
| OPEN IN-LINE CONNECTOR (BENT, PUSHED OUT OR CORRODED TERMINALS) |
