HMMWV New EESS NIINs --- EESS = Engine Electrical Start System

The spares procurement for EESS has led to another change which I will commonly refer to as the 1-piece design. Because of the different configurations, we have established a Generic NSN for EESS procurement purposes. The NSN is 6110-01-491-2158.

There will be three NSNs related to this generic NSN. They are as follows:

A.      6110-01-463-9260 –  2-piece design manufactured by KDS. This configuration contains a black control box with yellow label and a glow plug controller/temperature sensor with a yellow band. The temp sensor gets installed in the water crossover pipe.

B.      **6110-01-491-2142 – 1-piece design manufactured by KDS. This configuration contains a black control box with a bright green label. There is no longer a separate glow plug controller/temperature sensor required with this configuration. It will not make a difference whether the glow plug controller (2920-01-175-7214) or the temp sensor (2920-01-469-6903) is installed in the water cross over pipe. The pin to this lead is dead.

C.      **6110-01-491-2152 – 1-piece design manufactured by Signal and Systems, Inc. (SSI). This configuration contains a black control box and there is no separate glow plug controller/temperature sensor. It will not make a difference whether the glow plug controller (2920-01-175-7214) or the temp sensor (2920-01-469-6903) is installed in the water cross over pipe. The pin to this lead is dead.

D.     **6110-01-470-1931 – 1-piece design manufactured by KDS. This configuration contains a black control box and there is no glow plug controller/temperature sensor. It will not make a difference whether the glow plug controller (2920-01-175-7214) or the temp sensor (2920-01-469-6903) is installed in the water cross over pipe. The pin to this lead is dead.

 

There are NO Safety Issues related to these boxes/NSNs.

You should no longer get a blinking/flashing wait to start light when using the 1-piece design. The box should no longer go into default mode.

You no longer will need to troubleshoot the temp sensor/controller if you have the 1-piece design installed. However, be sure to keep the temp sensor/controller installed and connected.

Still need to make sure glow plugs are in good working condition- no need to automatically replace them, just check them.

Ensure that your connections to the body and engine side a good and tight.

The voltmeter will still fluctuate during after-glow activity. 

Bottom line - the one-piece design is the same as 2-piece design except for the temperature sensor.

If you suspect a problem with the starting system (control box):

1          Check batteries

2          Check all 8 glow plugs

3          If Wait to Start Light does not come on, but you had voltage gauge activity - attempt to start vehicle. If no start, check fuel system.


4          If Wait to Start Light comes on and you have voltage gauge activity, and still get a no start - your control box should be functioning, problem may be fuel related - check fuel system.

5          If no Wait to Start Light, no glow plug activity and no vehicle start; and all 8 glow plugs are good, wait to start light is good and connections at the body & engine side are good and tight, batteries are good - replace control box.
