FICM voltage Flucuates after repair..?

I sent my FICM into FICMrepair.com to be repaired. I just got the truck back from having headgaskets done, so i was finally able to drive it. I noticed that the voltage still flucuates between 46 - 48 volts. The batteries are good and tested good. The alternator is brand new and is producing 14.2 volts at idle and it still flucuates. Should it be flucuating? Thanks,

Will

I just got a FICM half shell replaced compliments of Ford, and the voltage fluctuates from 47.5 to 48.5 VDC. As long as it stays above 45 VDC then it's considered acceptable under Fords TSB.

It does fluctuate most of the time. I was told by FICMrepair.com that as long as it doesn't drop below 45 volts that it is fine and flucuating volts are normal.

What would cause the volts to flucuate that much once it is repaired? I thought that repairing it would keep it more of a constant steady voltage. The alternator is new and is putting out 14 volts, the batteries are about a year old and both tested good under load and are fully charged. I am just trying to make sure nothing is wrong after the repair. Thank you.

I was under the impression that the voltage should not drop below 48v. Mine is stock and sometimes fluctuates between 48.5 and 49 but has never dropped below 48. In fact, this morning it was at 48 with glow plugs on and jumped to 49 when cranking.
