Apache: Correctly Reinstall Generator Wires

BLUF:  Make sure Apache generator wire leads are marked properly so they can be reinstalled correctly after maintenance to prevent frying generators.

Dear Editor,

We have a lot of problems with wires being put on backwards after maintenance on the AH-64D/E No. 1 and No. 2 generators. And backward wires lead to fried generators.
The procedure in TM 1-1520-Lonbow/Apace (Mar 22) says to identify wires as they are removed. We once used tape or a grease pencil, 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-shrinkable bands with stamped stud numbers around the wire leads to avoid the wrong hookup. Here’s what we use:
Wire Tubing
T1 Black
T2 Blue
T3 Red
T4 Yellow

NSN 9390-01-494-3834 brings you a kit of heat-shrinkable bands.

Editor’s note: Great job! Identifying unmarked wires is always a problem and heat-shrinkable bands offer a good solution.
