Turn the brightness down so you don't burn a whole in the center of your monitor. In fact, if it is not "playing blind" you may want to unplug the monitor while you debug the game board.
I would recheck the fuses in circuit (with power off) by placing your meter probes on the holders as opposed to the fuses so you can verify continuity through the fuse and the holder.
I would also check that:
1) You didn't accidentally switch the game into test mode (maybe if you were cleaning the plate with the counter, volume control, etc.
If the fuses are all good, then I would take a moment to check how the connectors look to the game boards. Remove the connector and look into it to make sure the pins all look to be in good shape and not bent out of the way (I had a Warlords that behaved badly because one of the internal pins of the edge connector had been bent and was making contact to a neighboring pin. If they look good, reseat the connector and try to power it back up with the monitor unplugged.
2) recheck the voltages on the AR2
Do they still look good?

That's what I said before and should be the very first check to make.
Neverending Project:
I should mention that I did try both positions of the test switch. Am I correct in remembering that on boot it is silent until you add coins? Or will it be silent until I start a game?
Level42:
Depends. If it's set on free-play it will boot up with "May the force be with you" right away. If not, you'll have to credit it to hear that.
Something to check after transport: the interconnection board between the three PCB's.
Neverending Project:
OK, I re-checked the fuses on the clips and they all test good. I re-seated the PCB edge connectors on both ends of the board and checked the wire harness connectors as well. I also re-seated the molex connectors on the ARII board. I powered it up and checked both switch positions, turning the volume knob in both directions. I still get the spot killer on, and no playing blind.
I un-plugged the monitor and re-checked all the ARII test points. I still get -5.05V, +12.2V, and +/-23. Nothing changed.
If I listen closely to the speakers, I can hear some faint garbagy noise, but no talking or game sounds. To check the PCB test points, can I just pull the PCB boards out of the chassis and set them on something non conductive (like a board)? I mean they are still completely connected after I pull them out, right?
