Mark,

Test Points J6 & 7 are for reading the loop current. If it reads 0V between J6 & 7, that says the loop is open, which is why the Mite is running open. This could be due to a problem in the CV-2455, or in configuration of the Mite.

Short the loop connection at the Mite and read the voltage at J6 & 7. If OK, the problem is in the Mite. If no voltage at J6 & 7, then the problem is in the CV-2455.

(I have a PRC-47 & CV-2455, but never fired it up.)

Good luck,

I looked in the manual and part of the initial use says the test points J6 and J7 should show 0.2 VDC if not adjust R45, well I have zero volts with no change in adjusting R45 so I would say I have an issue.
