Dear Editor,
We had a problem with loose screws falling into the drain hole in the
Avenger’s slip ring during maintenance. When the Avenger was traversed,
a screw would tear up the slip ring and the cables running to it.
We stopped screws from getting into the slip ring by cutting a 3 x 3-in
piece of window screen and gluing
it over the drain hole. Silicone
adhesive is good for the gluing.
Water can still go through the drain
hole, but screws can’t.

Dear Editor,
The Avenger’s control display terminal is supposed to be set at 2100
for the minimum watt hours. That kicks on the battery warning light
when there’s 72 percent battery power left and tells the crew to start
the truck and recharge the Avenger’s batteries.
But sometimes that’s not enough warning, especially if we’re
operating remotely. Before the operator knows it, he has a powerless
Avenger.
We set the minimum watt hours at 2404 instead. That kicks on the
warning light when 80 percent battery power remains and gives the
operator an extra half hour to recharge the batteries. See Para 4-9c in
TM 9-1440-433-24-1 for instructions on changing the minimum watt
hours.

Thanks for the tip. The next change to TM 9-1440-
433-24-1 will say in Para 4-9.c to set the minimum
watt hours at 2350.
But, remember, crews, that the Avenger should
always be run with the slave cable connected. Also,
whenever possible, it should be operated with the
engine running so the batteries aren’t drained and
to prevent false errors and fault indications.
Operating with the engine running also makes it
unnecessary to power down the Avenger to start
the HMMWV.
When it is necessary to operate with the engine off, such
as during remote operations or simulating battle conditions,
gunners should keep an eye on the battery indicator and
recharge the batteries when there’s less than 85 percent
charge.
I think you’ve got the slip on that slip ring problem. Good job.
