re the instrument panel lights on your FMTV fashing on and o±±? I± so, you could
have a problem with the voltage regulator ±ound on the 260-AMP alternator.
A manu±acturer’s de±ect has led to internal ±ailures o± voltage regulators, NSN 6110-
01-559-2092, PN N3221. The ±ailure occurs during normal vehicle operations. Check
the reading on the voltage gages by the fashing light. In some cases, the voltmeter gage
reads in excess o± 32.48 volts, or reads no voltage at all!
Inspect the charging system using the -10 manual ±or the FMTV models in your unit:
•
LMTV/MTV A1R: IETM 9-2320-391-14&P
(PMCS Table 2, Item 16)

You must bring the vehicle up to operating temperature to get a good voltage
reading. I± no de±ects are ±ound, you’re good to go and no action is required. But i±
the system is ±aulty, noti±y ²eld-level maintenance ±or repairs.
Maintenance should remove and replace the voltage regulator using maintenance
task 07-05,
Voltage Regulator Replacement,
in IETM 9-2320-391-14&P. Note that
replacement regulators must be dated on or a±ter 09/09/09.
Voltage regulator replacement is an extended warranty item, so all costs will be
covered. I± your vehicle is out o± warranty, the voltage regulator replacement is still
covered under TACOM LCMC’s maintenance action message (MAM) 10-070. That
is,
if
your FMTV’s serial number is within the range given in the MAM. Note that
the MAM calls out the M1082 trailer, but that’s a mistake!
File a claim using TB 9-2300-426-15 and TB 9-2300-427-15. You must include
the unit’s identi²cation and truck serial number when submitting a claim. A±ter you
submit it, a new voltage regulator will be sent to you. Return the de±ective regulator
to the manu±acturer in the original shipping box.
You can also ²le a claim using the BAE warranty claim website:
You’ll have to create an account. No worries. The site is easy to use.
