Check VDB PDQ.

Loose hardware may be a problem on some -A3 Bradley and BFIST vehicle distribution boxes (VDB), NSN 6110-01-465-1847.

Loose bolts and washers can hold the bus bar against the circuit breakers, causing intermittent power loss and arcing. The VDB circuit breakers affected are CB13 (50-amp cold start switch), CB 14 (105-amp power unit access door switch), and CB20 (105-amp rear ramp switch).

If you find el VDB with one of the serial numbers, remove the vehicle ground cable if the VDB is inside the vehicle--following the instructions in WP 0582 00 in TM 9-2350-294 20-1-4. Then flip over to WP 0621 00 and follow the instructions for removing the VDB so you can turn it in to DS maintenance.

The complete scoop is in TACOM maintenance advisory message 06-003.

I DON'T GET IT. WE KEEP LOSING ELECTRICAL POWER!

HMM. SEEMS LIKE I REMEMBER READING SOMETHING ABOUT A VDB PROBLEM CAUSING THAT.
