37. The J 39200 instruction manual is a good source of information and should be read thoroughly upon receipt of the DMM as well as kept on hand for future reference A DMM should be used instead of test lamp in order to test for voltage in high impedance circuits While test lamp shows whether voltage is present a DMM indicates how much voltage is present The ohmmeter function on a DMM shows how much resistance exists between 2 points along a circuit Low resistance in a circuit means good continuity IMPORTANT Disconnect the power feed from the suspect circuit when measuring resistance with a DMM This prevents incorrect readings DMMs apply such a small voltage to measure resistance that the presence of voltages can upset a resistance reading Diodes and solid state components in a circuit can cause a DMM to display a false reading To find out if a component is affecting a measurement take a reading once then reverse the leads and take a second reading If the readings differ the solid state component is affecting the measurement Following are examples of the various methods of connecting the DMM to the circuit to be tested e Backprobe both ends of the connector and either hold the leads in place while manipulating the connector or tape the leads to the harness for continuous monitoring while you perform other operations or test driving Refer to Probing Electrical Connectors e Disconnect the harness at both ends of the suspe

Procedure You may need to load the vehicle in order to duplicate the concern This may require the use of weights floorjacks jackstands frame machines etc In these cases you are attempting to duplicate the concern by manipulating the suspension or frame This method is useful in finding harnesses that are too short and their connectors pull apart enough to cause a poor connection DMM set to Peak Min Max mode and connected to the suspect circuit while testing can yield desirable results Refer to Testing for Electrical Intermittents Certainly using the senses of sight smell and hearing while manipulating the circuit can provide good results as well There may be instances where circuit manipulation alone will not meet the required criteria for the fault condition to appear In such cases it may be necessary to expose the suspect circuit to other conditions while manipulating the harness Such conditions would include high moisture conditions along with exceptionally high or low temperatures The following discusses how to expose the circuit to these kinds of conditions Salt Water Spray Some compounds possess the ability to conduct electricity when dissolved in water such as ordinary salt By mixing table salt with water in sufficient quantities you can enhance the conductive properties of water so that any circuit which may be sensitive to moisture will more readily fail when liberally sprayed with this mixture Mixing 0
