J 42000 Battery Tester
Warning: Refer to Battery Disconnect Warning in the Preface section.
Note: The battery test using the J 42000 Battery Tester requires correct connections to the battery terminals. A failure to obtain the correct connections during the test may result in a failed test on a good battery.
If testing the vehicle with the battery cables still connected, wiggle the J 42000 clips on the terminal. This may cut through any coating or through any oxidation that may be present on the terminal.
Even new terminals contain a protective coating that may insulate or cause a resistance in the test circuit.
Warning: 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.
⇒ | If there is any apparent damage, replace the battery. |
⇒ | If the battery does not meet or exceed specifications, replace the battery. |
⇒ | If the battery cable(s) need to be cleaned, clean as required and tighten as specified. |
⇒ | If the battery cable(s) are damaged, replace then tighten as specified. |
⇒ | If the tester calls for charging the battery, refer to Battery Charging. |
Perform the Diagnostic Repair Verification after completing the diagnostic procedure.
