Dear Editor,
We have a lot of problems with
wires being put on backwards
after maintenance on the AH-64
No. 1 and No. 2 generators.
And backward wires lead to
fried generators.
The procedure in TM 1-1520-
238-23-5 says to identify
wires as they are removed. We
once used tape or a grease pen-
cil, but neither of those things
works. Oil smudges the markings
and heat makes the tape fall off.
Our idea is to use an
assortment of different colored
heat-shrink tubing with stamped
stud numbers around the wire
leads to avoid the wrong hookup.
Here’s what we use:
brings you the heat-shrink kit. If
you have problems ordering the
kit, contact Glen Heitland at
DSN 897-1419, (256) 897-
1419 or e-mail him at

rew chiefs, folding up your Kiowa Warrior’s .50-cal gun with the umbilical cable
still attached will strain and damage the cable and cage.
The cable is just not long enough to cover the added distance when you’re fold-
ing up the universal weapon’s pylon. When that happens, it could bend or snap the
bracket off the cage that holds the cannon plug and pull the connector off the cable.
To make matters worse, the cable is usually wrapped around the pylon mounting
arm to keep it out of harm’s way. This wrap makes the cable even shorter!
The simple solution is to disconnect the power cable before you fold the gun.

Great job! Identifying
ummarked wires is always a
problem and shrink tubing
seems like a good solution.
