Rob,

The whisker wires exiting the Cat and connecting to the terminal strip do not exactly sequence the terminal strip. I ALSO suspect that the sequence of connections to the terminal strip is different for the AC vs the DC radios. Follow the DC schematic:

Note the jump in the whisker count...

   

The terminal connections for power must match the DC battery strip connections.

   

The DC battery strip MAY not be the same as the AC strip, possible a lug in an incorrect position. That may be the problem.

Trace every connection from what we think is the correct DC power strip to the whiskers including the count for the whisker connections. That is the likely place for the error.

All assumes the cat passed the continuity test after the transformer replacement AND that the new jumper strip is correct... It is possible a return to C+ may be incorrect at the jumper strip or a short at one of the lugs.
