      Tech Tips


      • After disconnecting and reconnecting a cable to the auxiliary battery, the hybrid control system may not start on the first attempt. If this occurs, turn the power switch off. The hybrid control system will start normally from the second time onward.

      • When a cable to the auxiliary battery is disconnected and reconnected, the power source mode returns to the mode it was in before the cable was disconnected.
