Off hand, does anyone remember what size the compression fittings are on PCU?

Yes, your correct. My mistake...

Here’s a bit of extra information – this whole problem started shortly after leaving a car show where the vehicle was on display. During the day I had to hood up for the kids to see. Of course I noticed a couple of men standing next to engine on the driver side. One of these geniuses was between...

re: CTIS Pneumatic Controller Question Have an M923A2 with CTIS unit. System has been working fine for two years with no air leaks. One day I dropped the air pressure on the ECU to cross-country mode. The system aired down fine. When I went back to highway mode the pneumatic controller...

Resolve to possible chattering effect on pneumatic controller: Check for low supply air pressure to CTIS system. The gauges on the dash of the M923A2 are direct to the tanks. They do not reflect the supply pressure in the CTIS system. Typically the CTIS main air supply to the pneumatic...

Today I received a pair of 500 amp NATO connectors for a jump start kit. It was a bit over-kill but using 6 feet of 16/2 SO cord and one of the connectors changed out the plug on the BatteryTender station. The M35A2 is fully charged using a 2-pin NATO adapter and two of the M923A2 trucks are...

11.26.2014 - SIDE NOTE: I temporarily hard wired the BatteryTender.com charger to the batteries in the M35A2 vehicle just to verify the charger will turn “GREEN” when the batteries are fully charged. While posting my comments the charger did turn “GREEN” and I have a full 25 VDC at the battery...

- WARNING - PLEASE READ - Today I noticed after 5 days of “charging” the Battery Tender still said my batteries where not fully charged on the M35A2 I was testing it on first. I called the BatteryTender.com Company and spoke with the owner. We did some testing and discovered the NATO charging...

The J-6362/U Hummer Charging Cable is a standard NATO single pin charging cable with a built in fuse. This cable can be used for battery maintaining and/or connected to accessories. It uses a standard 3 pin connector found on 120VAC computer and battery equipment. You are going to cut it off…...

This is the NATO slave cable adapter. You can find these on the internet (I am not going to promote any one website or person selling these items, do some research) and have it shipped to your door. The NATO slave adapter is used to simply convert from the older style 2-pin auxiliary vehicle...

WARNING: 11.26.2014 - REVISED COMMENT: DO NOT PURCHASE THE J-6362/U NATO SLAVE CABLE CURRENTLY BEING SOLD ON EBAY! THE CENTER PIN IS NOT THE CORRECT DIAMETER FOR THE ORIGINAL SINGLE PIN NATO CONNECTORS ORIGINALLY INSTALLED ON THE M923 M939 M35 VEHICLES. READ ALL COMMENTS ON THIS PROJECT BEFORE...

RE: External 24 VDC Battery Maintaining Station Project Each year I store my vehicles for the winter months, remove the batteries and start a ritual of swapping 12VDC battery maintainers from bank to bank of batteries each week. This year I built a small 24VDC battery maintainer station that...

If the solar battery maintainers were originally installed by the U.S. Military in the vehicle they are 24VDC devices. They are connected to the same location as the end leads of the NATO plug. Just as shown in my diagram and the diagram found in the installation and operation instructions for...

Please refer to my previous electrical diagram: the M923A2 is a 24 VDC system. To use a solargizer system on this vehicle I would suggest purchasing 24 VDC units. Depending on the wattage these devices are rated for, you may want to use two of them in parallel to decrease the charging time and...

Please see the TM's as the 12 Volt lead is required for normal vehicle operations. The wiring diagram under the M923A2 passenger seat explains the connection point requirement.

Here are a couple of pictures from the old battery box. In a previous post I included the wire diagram for connecting the batteries in series to get your 24 volts; then paralleled them with another set of batteries to double up the cranking amps. Most of you should still have your battery wiring...

Here is a diagram of the battery connections. I purchased 25’ of #2 S.O. cable from the local electrical shop. This is the same size cable that is currently installed in the vehicle. The only difference is the cable the military uses has a heavy rubber hose over the copper instead of a thinner...

I will post the rest of the pictures tomorrow. I have the wire harness down and the connection terminals to reconnect the original leads to the truck.

Batteries: Go down to your local “Batteries Plus” and pick up four (4) 1100 Amp Duracell ProCell batteries for about $98 each. These have more than enough cranking amps to turn over a 5 ton and run your lights for a while when you forget to turn off the switch. As for the battery holder: I went...

I used some 1/2" angle iron and welded two sticks on the right & left (outside) of the box. This will serve as a better shelf for the cover to sit back on. The original box lid already had an overhang, so this worked out well to rest my new cover on - and also added a stick to the back (inside)...
