it seems that the screen on my tempest shuts off any time the voltage into the machine fluctuates at all. like, if i put it into a power strip with any other games, or even plug a game into the same circuit. i was told by jeff at arcade adventures to check voltages on the AR2 board and make sure they are all there. is there any thing else this could be?

it plays fine for a while, but is just temperamental and i am pretty sure its being sensitive to power... any ideas?
 
First thing to do is ensure the monitor molex connector pins are clean, tight and in the connector correctly. Over time those have a tendency to get loose and/or pull out of the connector.
If those check out ok then turn the machine on and let it run for 10-15. Then take a B+ reading.
The B+ might be a tad low as it sits - needless to say if it droops any more that would also cause issues.
