J 39200 Digital Multimeter
Perform the following procedures while wiggling the harness from side to side. Continue this at convenient points (about 6 inches apart) while watching the test equipment.
If the fault is not identified, perform the procedure below using the MIN MAX feature on the J 39200 DMM. This feature allows you to manipulate the circuit without having to watch the J 39200 . The J 39200 will generate an audible tone when a change is detected.
NOTE:
The J 39200
must be used in order to perform the following procedure since the J 39200
can monitor current, resistance or voltage while recording the minimum (MIN), and maximum (MAX) values measured.
