DD15 Operator Guide – Emergency Jump Starting

Emergency Jump Starting

The DDEC VI system operates on 12 volts DC. If a DDEC VI engine with an electric starting motor requires emergency jump starting, do not exceed 16 volts DC.



To avoid injury from battery explosion when jump starting the engine, do not attach the cable end to the negative terminal of the disabled battery.‪


Jump starting with voltages greater than those indicated or
reversing battery polarity may damage the Motor Control Module.‪


Failure to connect jumper cables in the proper sequence can result in alternator and/or equipment damage.‪

Before attempting to jump start the engine, make sure the jumper cables are connected properly (positive to positive, negative to chassis or suitable ground) and in the proper sequence (negative to negative ground last


Battery Explosion and Acid Burn

To avoid injury from battery explosion or contact with battery acid, work in a well ventilated area, wear protective clothing, and avoid sparks or flames near the battery. If you come in contact with battery acid:‪

  • Flush your skin with water.
  • Apply baking soda or lime to help neutralize the acid.
  • Flush your eyes with water.
  • Get medical attention immediately.
