Circuit/System Verification


1. Ignition OFF, measure and record the battery voltage at the C1 Battery terminals. The voltage should be between 12.0-15.0 V.

2. If not within the specified range, refer to Battery Inspection/Test .

3. Remove the drive belts. Refer to one of the following:

• Drive Belt Replacement for the 2.0 L engine

• Drive Belt Tensioner Replacement for the 2.0 L engine

• Drive Belt Replacement for the 2.0 L (Diesel) engine

• Drive Belt Tensioner Replacement for the 2.0 L (Diesel) engine

• Drive Belt Tensioner Replacement for the 2.8 L, 3.0 L, 3.2 L, or 3.6 L engine

• Drive Belt Replacement for the 2.8 L, 3.0 L, 3.2 L, or 3.6 L engine

4. Using the appropriate tools, rotate the crankshaft by hand and verify the crankshaft rotates.

5. If the crankshaft does not rotate, refer to one of the following:

• Engine Will Not Crank - Crankshaft Will Not Rotate (LDK, LHU) for the 2.0 L engine

• Engine Will Not Crank - Crankshaft Will Not Rotate for the 2.0 L (Diesel) engine

• Engine Will Not Crank - Crankshaft Will Not Rotate for the 2.8 L, 3.0 L, 3.2 L, or 3.6 L engine

6. Ignition ON, attempt to start the engine. Make sure the crankshaft is rotating.

7. If the engine cranks, inspect the engine and belt drive system for mechanical binding, seized engine, or seized generator.

8. Verify that a test lamp illuminates between the M64 Starter Motor B+ terminal A X1 and ground.

9. If the test lamp does not illuminate, test the B+ circuit for a short to ground or an open/high resistance.

10. Test for less than 0.5 V between the positive battery cable and terminal A X1 at the M64 Starter Motor as ignition is switched to start position.

11. If greater than the specified value, replace the positive battery cable.

12. Test for less than 0.5 V between the negative battery cable and the M64 Starter Motor case as ignition is switched to start position.

13. If greater than the specified value, replace the negative battery cable.

14. If all circuits test normal, replace the M64 Starter Motor.
