Welcome to the club!

You're going to want to read most of Phil's definitive Bally Bingo site, probably starting from here:
https://bingo.cdyn.com/techno/overhaul/

As for your specific questions:
"Tilt at initial power up." -- As designed.
"Red scores do not appear at first but sometimes at random after several plays cycled, sometimes not at all." -- Clean the red scores unit.
"Yellow and Green do not appear until second coin played." -- Check the bulbs themselves; clean both yellow and green scores units.
"Able to move screen and collect replays at first, then 6 volt 10 amp fuse lets go and out go the lights (all feature lights)." -- That will take some troubleshooting from someone more experienced than me.

I expect you'll get some additional help from this group.

Do you know the history of the machine? Was it ever on location? I suspect that it was, since it was not uncommon for some operators to disable the highest-paying features on their machines, such as 2 in the blue on Circus Queen.

In any event, it sounds like you're on the right track. Go ahead and attach the wires on the 2 in the blue per the schematic and then retest.

Cheers!

While you're at it, check that the reflex units were not altered. See my complete write up, with photos, here:
