Dear Editor,
I’m an instructor at Aberdeen Proving Grounds, MD, for our Track
Division. I instruct professional development automotive courses for NCOs
and warrant officers.
We can’t operate all of our equipment on a regular basis, so it has
been very challenging to keep the batteries properly charged.
Uncharged
batteries keep our students from doing hands-on troubleshooting and
training whenever necessary.
We overcame this problem by using the ground power unit (GPU) you
listed on Page 8 of PS 622 (Sep 04).
The GPU keeps the batteries on
our tracked vehicles fully charged all the time.
We’ve used the GPUs for
the last two years with no lost training time.
We train well over 1,000 warrants and NCOs every year, but I am still
amazed at how many of our students are unaware of the availability and
capability of these units in the field.
Since it’s been a few years, could you let Soldiers know about the
benefits of these GPUs?

II
Regulator Valve
Use NSN 4820-00-551-1094 to get the regulating flow valve for the acetylene bottle
shown in the M88A1 recovery vehicle’s basic issue items (B
II
). This NSN replaces the
one shown as Item 39 on Page B-11 of TM 9-2350-256-10.
Editor’s note:
You bet, Sir!
The most common GPU used for combat vehicles is
the TIMV3000, NSN 6130-01-475-5321.
This GPU is a Class II item, weighs only 125 pounds and has wheels, so it’s
easy to move between vehicles.
You can recharge the GPU in about 75 minutes from a 110/220-volt or 240-volt
outlet.
In the Feld, you can pull a 24-volt back-charge from your vehicle through
the NATO slave cable.
With the GPU, a maintenance team in a small vehicle can make repairs to a
disabled vehicle, re-start it and send it back into action without needing another
vehicle to provide slave power.
The GPU also gives units the ability to operate
under “silent watch” for short periods of time.
Based on feedback from Soldiers, the GPU now includes the following
improvements:
• Hardwired AC line cord
• Run-flat tires
• Resettable circuit breaker
The GPU works great with all combat, tactical and construction vehicles—
anything that uses a 24-volt system.
Check out the manufacturer’s website:
There you’ll Fnd more information about this and other GPUs, including the
TIMV1000, NSN 6130-01-457-5313, the TIMV3000’s “little brother.”
• Axle extensions
• Telescopic handle
• Rugged shipping case
