put finger to keyboard and composed:

At a glance, 0.6 volts at pin 8 is wrong - capacitor C312 should charge up
through R364.

If it is held low, the thing will never turn on.

AISI, pin #8 should go low if either pin #1 or pin #7 are high, or if
either pin #2 or pin #3 are outside the range of -0.7V to +0.7V.

If there is a fault condition, one or more of Q6, Q18, and Q19 will be
on. This means that Q10 will be off and Q11 will be on. This in turn
means that Q12 and Q13 will be off and the relay will be open.
