3. Place the S39 ignition switch to the CRANK position.

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

4. Test for less than 0.5 V between the positive battery cable and terminal A X2 at the M64 starter motor as the S39 ignition switch is placed to the CRANK position.

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

5. Test for less than 0.5 V between the negative battery cable and the starter motor case as the S39 ignition switch is placed to the CRANK position.

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