Cold Start Heater Current Draw Faulty.
Have assistant turn engine start switch and starting aid switch to ON position (TM 5-3895-379-10).
The current draw should be 16 to 18 amperes at 12 volts.
Turn engine start switch to OFF position (TM 5-3895-379-10).
Turn battery disconnect switch to OFF position (TM 5-3895-379-10).
If current draw is more than 18 or less than 16 amperes, replace cold start heater
(WP 0130). Close left and right-side door assemblies (TM 5-3895-379-10).
If current draw is between 18 and 16 amperes, remove clamp on multimeter and go to next
Cold Start Heater Leaking Fuel.
Remove fuel line and cold start heater from intake manifold (WP 0105).
Particles blown by compressed air are hazardous. DO NOT exceed 15 psi
(103 kPa) nozzle pressure when drying parts with compressed air. Use a maximum
of 30 psi (207 kPa) when cleaning components. DO NOT direct compressed air
against human skin. Failure to follow this warning may cause injury or death. Make
sure air stream is directed away from user and other personnel in the area. To
prevent injury, user must wear protective goggles or face shield.
Connect an air supply with maximum 20 psi (140 kPa) to fuel inlet passage of cold start heater.
Submerge cold start heater in a container of clean diesel fuel for 10 seconds.
No air bubbles should be visible from cold start heater.
If bubbles are visible from the cold start heater, replace cold start heater (WP 0130).
If bubbles are not visible from the cold start heater, install cold start heater (WP 0130) and
notify supervisor that engine exhaust smokes excessively.
