If this is unsuccessful, use local cooling treatments such as ice or a venturi type nozzle (one that provides hot or Once the vehicle, component, or harness has been sufficiently cooled, manipulate the harness or components in TESTING FOR ELECTRICAL INTERMITTENTS Perform the following procedures while wiggling the harness from side to side. Continue this at convenient z Testing for Short to Ground z Testing for Continuity z Testing for a Short to Voltage If the fault is not identified, perform the procedure below using the MIN MAX feature on the J 39200 DMM. 1. Connect the J 39200 to both sides of a suspected connector (still connected), or from one end of a suspected circuit to the other. Refer to Troubleshooting with a Digital Multimeter for information on 2. Set the rotary dial of the J 39200 to the V (AC) or V (DC) position. 3. Press the range button of the J 39200 in order to select the desired voltage range. 4. Press the MIN MAX button of the J 39200 . The J 39200 displays 100 ms RECORD and emits an audible tone (beep). 5. Simulate the condition that is potentially causing the intermittent connection, either by wiggling the connections or the wiring, test driving, or performing other operations. Refer to Inducing Intermittent 6. Listen for the audible Min Max Alert which indicates that a new minimum or maximum value has been recorded. 7. Press the MIN MAX button once in order to display the MAX value and note the value. 8. Press the MIN MAX button again in order to display the MIN value and note the value. 9. Determine the difference between the MIN and MAX values. IMPORTANT: 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 IMPORTANT: The 100 ms RECORD mode is the length of time an input must stay at a new value in order to record the full change.
