Hoping someone knows enough about the insides of a zilla to answer this;
The serial communication going to the big box, what readings is it looking for?
The big box in my zilla died but the hairball is fine, so I'm thinking to make a big of mosfets and caps to replace it.

Why not contact Manzanita Micro and ask them to repair your HV unit? They have a good support team and I still suppor the Zilla...
