Crumar Musical Instruments User Group.

I am hoping someone else has run into this problem and can make some
suggestions. I posted this a while ago and sadly, no intereste or response.
So I bought a Crumar T2 organ off of Ebay that needed work. I know
I must be a glutton for punishment when it arrived and I flipped open the lid
and raised the keyboard assemblies (nice design) and many of the cards were out
of place.
I sourced a schematic and got all the cards back in place, soldered some loose
connections, replaced damaged caps and diods on a few cards and boards and fired
her up to find that the lower board worked perfectly, but the upper board would
only make the key click sound.
I have several keyboards and one of them being a hammond, so I am sure i have
the settings right.
The biggest idenitifier of an issue is that the Bus cable that connects the
bottom row of cards (the interlaced cards under the keys) from the left side to
the right had been unplugged and was laying in the bottom of the keyboard. I
thought, great, just plug this in and i will get my upper keys working. when i
plugged each end in to the appropriate card (front cards), I hear what sounds
like all the keys playing at once, and the bottom can be faintly heard through
the noise. the top keys still dont generate any organ sounds, just the key
click. I know we want the key click, but i can't figure out where the problem
might be and where to look for issues with chips,
loose connections, etc. perhaps the last guy in there misswired it in a repair.
unfortunately, this t2 has been heavily abused. that being said, i have to
imagine that since i am getting everything to work perfectly on the bottom board
that it's worth pushing through and getting this organ up and running. Anybody
have any ideas? also, i only have the schematics to the T1 and although it is
very helpful, it most likely doesnt give me all the info i need. Thanks to
anyone that can make some suggestions on where to dig in.
