GI problems WCS

This machine is haunted. I swear. and I've been swearing a lot!

Left side GI is out. I put a new header on J121 and plug , new pins. Pin 9
is the problem on J121121. I've buzzed it out to the fuse and back to pin 6
on J115(which also has a new header).

With J121 disconnected I have power to the circuit. The moment I connect the
plug- nothing. J120 is not used on WCS so I think OK- cracked header pins
perhaps and plug into J120. The same problem.

Maybe the circuit is failing under load? So I short pin 9 to 10 on J121 and
the circuit works fine.

This cicuit was working after the plug repairs but I did notice it "flutter"
the other day. I can't make it flutter now.

Stumped again. Suggestions anyone? (I thought triac but I'd be surprised-
Clay has never replaced one)
