Engine Cranks Slowly
Inspect the following items:
• Battery—Perform the Battery Inspection/Test. Refer to "Battery Inspection/Test".
• Wiring—Inspect the wiring for damage. Inspect all connections to the starter motor, the solenoid, the battery, and all
ground connections. Refer to:
– "Circuit Testing: "
– "Wiring Repairs: "
– "Testing for Intermittent Conditions and Poor Connections: "
– "Connector Repairs: "
• Engine—Verify that the engine is not seized.
If the battery, the wiring, and the engine are functioning properly, and the engine continues to crank slowly, replace the
starter motor. Refer to "Starter Motor Replacement: ".
Battery Inspection/Test
Special tool
J 42000 Battery Tester
Diagnostic Aids
NOTE
• Failure to properly understand the battery and its function could lead to a misdiagnosis and
unneeded repairs. Refer to "Battery Description and Operation" and "Battery Common Causes of
Failure" for more information.
• If testing an AGM battery with the J 42000, add 100 to the CCA rating of the battery and enter that
amount into the tester when prompted for the CCA rating. For instance, if the AGM batteries CCA
rating is 500 amps, enter 600 into the J 42000. Perform this modification only if the J 42000 does not
ask if you are testing an AGM battery. If these instructions are not followed when testing an AGM
battery, an invalid test result and invalid test code will be obtained on the J 42000.
• The battery test using the J 42000 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.
• When the J 42000 inquires "has the battery been charged", answer yes only if the battery has been
charged on this visit to the dealership.
Follow these instructions in order to avoid an incorrect diagnosis because of connections:
• If testing the vehicle with the battery cables still connected, wiggle the J 42000 clips on the terminal bolt. This may
cut through any coating or through any oxidation that may be present on the bolt.
Even new bolts contain a protective coating that may insulate or cause a resistance in the test circuit.
• If correct connections to the battery terminal bolts in the vehicle are in doubt, perform the following steps:
a. Disconnect the negative battery cable.
b. Disconnect the positive battery cable.
c. Install the test adapters on the terminals.
d. Follow the instructions for an Out-of-Vehicle test.
• If the tester displays a REPLACE BATTERY or BAD CELL-REPLACE result for a battery tested in the vehicle with
the battery cables connected, perform the following steps:
a. Disconnect the negative battery cable.
b. Disconnect the positive battery cable.
c. Install the tester adapters.
d. Follow the instructions for an Out-of-Vehicle test.
e. Replace the battery only if the Out-of-Vehicle test shows a REPLACE BATTERY or BAD CELL-REPLACE
result. This prevents battery replacements that are due only to faulty battery cable connections.
