HMMWV FUSE AND RELAYS-LOCATIONS?

This link is to all of the manuals.


The main things to remember when looking through the manuals are that the M1123 is an "A2" truck. It's equivalent to an M998A2 with a few modifications that the Marine Corps wanted, and thus got it's own designation.

example, see the header:
example 1.jpg


Another thing to remember is when going through the parts manual (the TMs with "-P" at the end of it) is that the UOC (Use On Code) for the M1123 is "NNN"
This means when you are looking at parts, and find the correct diagram, then part number and description, if it's specific to a certain model or models, there will be a UOC

Example, look at the red circles:
Example 2.jpg


If there is no UOC listed, then the part is universal to every model of HMMWV


And yet another thing to pay attention to is that there are two different serpentine belt configurations, usually listed as "before Litens" and "after Litens" for parts. In the manuals it's also commonly listed as "pre 196900 serial number" and "post 196900 serial number" or similar description. Then to make it worse is sometimes a post 196900 serial number engine gets put in a truck with the pre 196900 serial number truck. Easiest way to tell is if the power steering pump reservoir is built into the pump assembly, or if the reservoir is remote. Extremely easy to tell them apart if you know what either of the power steering pump reservoirs looks like. The first example above is power steering pump with built in reservoir, and the example below is the one with remote reservoir.

Hard part is that nobody bothered to say that the M-1123 is also called a M1114 Series Truck. In other words, the Expanded Capacity Vehicles (ECV) of the M1114 series – m1113, m1114, m1115, m1116, m1121, m1123, m1124, m1145 FAC, m1151, m1152, m1165, m1167

The -10 TM is available for download here:

The repair parts and field maintenance is also here for the newer models:
Great. Thanks much.

This is great thanks. I guess I am not sure now what platform is actually sitting in my garage that I am working on...

Do you know how I can identify what my platform actually is? 1123 and or a 1114 etc?

And what year it is so I can have a baseline for TMs etc?

The NSN is 2320-01-455-9593 (this is generic I assume for the platform)
The original serial was/is 224734
The USMC stock number is 613401.

The only known so far is that this truck had a MAK done in 2010 in Barstow where they added armor, springs and AC (which by the way will not come on, hence my original post) and that at that time it had about 1800+/- miles on it and has about 3800 on it now.

Look at the data plate in the driver door jamb. Does it show m1123 or m1114? Post a pic of the front of the truck. Those 2 models have different hoods, front ends, engine, roof, etc

MAK a was only added to M1123’s, M1114’s used the BAE armor kits, has turbo motor and extended snout for longer radiator, you have an M1123.

Two 15 amps behind dash are for Heater fan, and other to gages.
4l80e trucks have a breaker behind batt. box on a panel.
Light switch has a built in breaker.
There are fuses for other systems on M1151/65/67 trucks behind batteries on horizontal B pillar area.
