Hello Brian,
I had a similar problem with another P6 which I had in for repair.
One of the quad latches was running out of control because the
control port line from the CPU was missing. I see from your picture
there is still some severe corrosion on the print which needs to be
dealt with post haste! I would suggest you start looking from broken
tracks around the area where IC31 is and the new battery has been
mounted.
Cheers,
Andy
