Emergency Jump Starting

Emergency Jump Starting - Ops

The engine's electronic system operates on 12 volts DC. If a DD Platform engine with an electric starting motor requires emergency jump starting, DO NOT EXCEED 16 VOLTS DC.

Warning: BATTERY EXPLOSION

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.

Warning: 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.
Notice: Jump starting with voltages greater than those indicated or reversing battery polarity may damage the MCM.
Notice: Failure to connect jumper cables in the proper sequence can result in alternator and/or equipment damage.

Before attempting to jump start the engine, the jumper cables must be connected properly; positive-to-positive, and negative-to-chassis or suitable ground. The proper sequence is to connect negative to negative ground last.
