Circuit/System Testing

WARNING: This page is about a different car, the 2015 Chevrolet Trax and 2015 Buick Encore. However, it is still accessible from the selected car via links, so may be relevant.
  1. Ignition OFF, measure and record the battery voltage at the C1 Battery terminals.
  2. Verify the measured voltage is between 12-15 V.
    • If voltage is between 12-15 V 
  3. Remove the drive belts. Refer to Drive Belt Replacement
  4. Verify the crankshaft rotates. Rotate the crankshaft by hand using the appropriate tools.
    • If the crankshaft rotates 
  5. Verify the engine does not crank when attempting to start the vehicle.
    • If the engine cranks 

      Inspect the engine and belt drive system for mechanical binding, seized engine, or seized generator.

    • If the engine does not crank 
  6. Verify that a test lamp illuminates between the M64 Starter Motor B+ terminal A X2 and ground.
    • If the test lamp does not illuminate and the circuit fuse is good 
    1. Ignition OFF.
    2. Test for less than 2 Ω in the B+ circuit end to end.
      • If 2 Ω or greater, repair the open/high resistance in the circuit.
      • If less than 2 Ω, verify the fuse is not open and there is voltage at the fuse.
    • If the test lamp does not illuminate and the circuit fuse is open 
    1. Ignition OFF.
    2. Test for greater than 100 Ω between the B+ circuit and ground.
      • If 100 Ω or less, repair the short to ground on the circuit.
      • If greater than 100 Ω, replace the M64 Starter Motor.
    • If the test lamp illuminates 
  7. Test for less than 0.5 V between the positive battery post and M64 Starter Motor B+ terminal A X2 with the ignition in the START position.
    • If 0.5 V or greater 

      Replace the positive battery cable.

    • If less than 0.5 V 
  8. Test for less than 0.5 V between the negative battery post and the M64 starter motor case with the ignition in the START position.
    • If 0.5 V or greater 

      Replace the negative battery cable.

    • less than 0.5 V 
  9. Replace the M64 starter motor.
