f you have a new A3 Bradley or A3 BFIST turret drive control unit or the A12 or
A13 circuit cards have recently been replaced, you may be getting false faults.
The faults are caused by A12 (PN 1298633) and A13 (PN 12986337) circuit
cards. They can cause false faults when you run the vehicle diagnostic management
(VDMS) gun elevation and TOW elevation tests using A12 and A13 circuit cards
with Intel A80486DX4WB100 processors with a vehicle version identi±cation
(VVID) not upgraded to the 8.00.15-18 con±guration.
The false faults are fault code 40210 (gun elevation brake set
test) and 40310 (TOW elevation brake set test). The faults can
be ignored if no other turret functional problems occur.
This circuit card problem is corrected by MWO 9-2350-
294-30-19, which installs VVID 8.00.15-18. Schedule
your A3 Bradleys for the MWO. If you receive
new A3 Bradleys, use your maintenance support
device (MSD) to make sure their VVID has
been upgraded to VVID 8.00.15-18.
Dear Sergeant G.A.B.,
Keep those coins in your pocket,
Sergeant. Item 28, NSN 2510-00-703-
5900 (PN 7035900), is the left torsion
bar. Item 29, NSN 2510-00-703-5899
(PN 7035899), is the right.
Since there’s no way to tell which
one’s which from the drawing, make a
note in your TM.
Dear Half-Mast,
The left and right torsion bars for the M88A1 recovery vehicle are
Items 28 and 29 in Fig 192 of TM 9-2350-256-24P-1.
Our problem is that the TM doesn’t specify which is left and which is
right. We only need one torsion bar and we’d rather not flip a coin.
Can you help us out?
