[RE-wrenches] 0% on FNDC readings yesterday and today

[John Blittersdorf]

Nick,
    I had the same call from a customer reporting 0% today.  The batteries
are (5) Fortress e-Flex 5.4  The preassembled Radian came with the flexNetDC
which I normally don't install for the same reasons.  I was stumped until
now.  Obviously there is a problem with Optics or the FNDC.
