[1000mp] Help InRad Key Click mod

[Art Searle W2NRA]

Help!

I'm having trouble with the InRad Key Click mod.

Today, before I installed the Key Click mod I did
the IF mod and the Bonus mod.  I tested the radio
and all worked fine.

Then I installed the Key Click mod.  The radio
works fine except that the CW filters don't work.
I have no optional SSB filters in it but I do have
all of the CW slots filled, 500 and 250.  For the
record, when working on the filter board I only
removed the 2 ribbon cables and folded it over
onto a towel to work on the bottom.

Any ideas?  Where should I look?
