Remove all jewelry such as rings, dog tags, bracelets, etc. If jewelry or tools contact positive electrical

circuits, a direct short may result. Damage to equipment, injury or death to personnel may occur.

Allow engine to cool before performing troubleshooting maintenance. If necessary use

insulated pads and gloves. Hot engine components will burn and cause personnel injury.

Use jumperwire only between terminals indicated.

Failure to comply may result in damage to DDEC

components or wiring.

RESISTANCE TEST

(1) Loosen screw and disconnect engine

harness connector at DDEC ECM.

(2) Place jumperwire between terminals B

and A at TBS harness connector.

(3) Read resistance between wires 432

and 452 at engine harness connector,

terminals P1 and Y2.

(a) If there are more than 5 ohms

present, remove jumperwire and

repair wires 432 and/or 452

(see schematic Fig 2-2) or

notify DS Maintenance.

(b) If there are 5 ohms or less

present, remove jumperwire and
