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

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

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.

RESISTANCE TEST

(1) Disconnect TBS harness connector.

(2) Are there more than 10,000 ohms or

an open circuit present between

wires 416 and 452 at TBS connector,

terminals A and C?

(a) If less than 10,000 ohms are

present repair wires (see

schematic Fig 2-2) or notify DS

Maintenance.

(b) If there are more than 10,000

ohms or an open circuit, wires 416

and 452 are OK. Perform Step (3)

below.

(3) Are there more than 10,000 ohms or

an open circuit present between

wire 416 at TBS connector,

terminal C and a known good ground?

(a) If less than 10,000 ohms are

present repair wire 416 (see

schematic Fig 2-2) or notify DS

Maintenance.

(b) If more than 10,000 ohms are

present or an open circuit, wire

416 is OK. Go to Step 4 of this

Fault.
