I have one of those.  There is some adjustments in the same area where you switch between 60/20 and a couple of test points to verify.  Also check the fuse as that only supports the loop current and not the blower I have found that sometimes there is just the smallest amount of corrosion.   Its a pretty stout unit so hopefully something simple if not its not to complicated to fix.

So nothing like waiting until 20 minutes before the ratt net to check your equipment right ?.

  I have a new to me CV-2455 I have installed on the PRC-47, I have a shielded cable going from the CV tty loop posts going to my Mite, I checked and the polarity is correct and is showing 25vdc, power switch on the cv is on.  The problem is the Mite runs open, when I switch the 47 to cw/fsk the 47 transmits and the blower comes on.  Is my cv bad or am I not doing something right ?
