Cold Cranking Test

WARNING: This page is about a different car, the 2022 Chrysler Voyager and 2022 Chrysler Pacifica. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:

For complete starter wiring circuit diagrams Appropriate Service Wiring Diagrams. The battery must be fully-charged and load-tested before proceeding. Refer to BATTERY .

1 - POSITIVE CLAMP
2 - NEGATIVE CLAMP
3 - INDUCTION AMMETER CLAMP
  1. Connect volt-ampere tester (1) and (2) to battery terminals. See instructions provided by manufacturer of volt-ampere tester being used. Note: Certain diesel equipped models use dual batteries. If equipped with dual battery system, tester should be connected to battery on left side of vehicle only. Also, tester current reading must be taken from positive battery cable lead that connects to starter motor. 
  2. Fully engage parking brake.
  3. If equipped with manual transmission, place gearshift selector lever in Neutral position and block clutch pedal in fully depressed position. If equipped with automatic transmission, place gearshift selector lever in Park position.
  4. Verify that all lamps and accessories are turned off.
  5. To prevent a gasoline engine from starting, remove either the ignition run fuse, or the fuel pump control fuse.
    WARNING:

    Attempt to start engine a few times before proceeding with following step.

    NOTE:

    A cold engine will increase starter current (amperage) draw reading, and reduce battery voltage reading.

  6. Press and hold the ignition in Start  position. Note cranking voltage and current (amperage) draw readings shown on volt-ampere tester.
    1. If voltage reads below 9.6 volts, refer to STARTER MOTOR . If starter motor is OK, refer to DIAGNOSIS AND TESTING for further testing of engine. If starter motor is not OK, replace faulty starter motor.
    2. If voltage reads above 9.6 volts and current (amperage) draw reads below specifications, refer to FEED CIRCUIT TEST  .
    3. If voltage reads 12.5 volts or greater and starter motor does not turn, refer to CONTROL CIRCUIT TESTING .
    4. If voltage reads 12.5 volts or greater and starter motor turns very slowly, refer to FEED CIRCUIT TEST .
