J 39200 Digital Multimeter
Excessive resistance caused by poor terminal connections and partial short circuits through worn cable insulation will result in an abnormal voltage drop in the starter cable. Low voltage at the starter will prevent the normal starter operation and cause hard starting.
Whenever the battery cables are replaced, use a replacement cable that is the same in the type, the diameter, and the length. Some positive cables have additional feed wires attached to them and some of the negative cables have additional ground leads attached.
Caution: In order to prevent possible personal injury from a moving vehicle or from an operating engine, perform the following steps before performing the checks:
Place one probe of the J 39200 on the grounded battery post (not on the cable clamp) and the other on the frame.
Operate the starter and note the voltage reading.
In order to eliminate resistance, the cables should be disconnected and the connections should be cleaned.
If the cables are frayed or the clamps are corroded, the cables should be replaced.
When selecting the new cables, ensure that the new cables are the same length and the same diameter as the original cables being replaced.
Caution: Unless directed otherwise, the ignition and start switch must be in the OFF or LOCK position, and all electrical loads must be OFF before servicing any electrical component. Disconnect the negative battery cable to prevent an electrical spark should a tool or equipment come in contact with an exposed electrical terminal. Failure to follow these precautions may result in personal injury and/or damage to the vehicle or its components.
Notice: When installing the positive battery cable to the starter solenoid, the inner nut on the solenoid battery terminal must be tightened before the battery cable and the other leads are installed. Failure to do so will result in the solenoid or the solenoid terminal damage.
Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.
