    1. Remove the steering column lower cowl
    2. Set the ignition to on
    3. Set a multimeter to measure voltage
    4. Using the multimeter, measure and record the battery voltage (reference voltage)
    5. Connect the multimeter to clockspring connector C2LS41H terminals 7 and 8

      Does the multimeter display < battery voltage?
