Circuit/System Testing

  1. If the DTC is history, refer to Charging System Test .
  2. If the DTC is current, turn ON the ignition, and with a DMM, measure the voltage between the battery positive voltage circuits of the ESC and the ground circuits of the ESC.
    • If the voltage is within 9.5-15 volts, replace the ESC.
    • If the voltage is not within 9.5-15 volts, measure the voltage between the battery positive voltage circuits of the ESC and a separate good ground.
    • If the voltage is within 9.5-15 volts, test the battery positive ground circuits of the ESC for high resistance or an open, and repair as necessary.
