merlin 1030 power module info needed 1

[lar42]

Hello - Can any one help. On a Merlin 1030 system they are having inttermittant station ringin failures. I suspect flaky power module ( although no alarms indicated ) tried measuring voltages on front of power module circuit card .
I had DC voltages @ 50 volts on both (Aux jacks) but could not measure any AC or Dc voltages on the ( ringing Gen ) pins (jack ) Question should there be voltage present at this point ?

No, Those are inputs for ring gen. and are used for the 10 basic station module...
