Verify Starter Motor -B- low current circuits are operating correctly by listening for the Starter Relays -J906-, -J907- to
click or verify voltage at the Starter Relays when Starter Motor -B- doesn’t engage. If the low voltage side of the circuit
can be eliminated as a potential cause of the issue, or if the vehicle is currently starting, check the high current portion
of the Starter Motor -B- circuit proceeding as follows:
Tip:
The following areas need to be checked while the engine is cranking.
1. Voltage drop test the Positive Battery Cable from the positive post of the Battery to Starter Motor -B-.
2. Voltage drop test the Negative Battery Cable from the Negative Battery Post to the Jump Start/Charging Post in the
engine compartment.
3. Voltage drop test the Negative Battery Cable from the Frame Rail to the Transmission Ground Post.
If any are over 0.3V, replace the suspect cable. If the voltage drop is not excessive, replace Starter Motor -B-.
