ok so two part plan was to get a know working power brick and parts to fix the old and incase there was an issue. I got the power block today and a guy had indicated that it was tested and working with pictures of the game working from this forum. I beleive the game and brick are in working condition. I ran some test with just the power brick first and got the flowing results using a foum link below that someone suggested as the volts I would get from the power brick. I would like to see if any of you have any ideas on how I should preceed since even just the power block seems to not have the power outout that is suggested by the arcade form link in the below email. and this is the first item in the chain.
Also I tested the input wire from the wall and got 170 vac (white and black) and the same vac with green and black (common)

Meter set to 20vdc
Red lead to pins 1, 2, 3
Black lead to pins 4, 5
Reading should be 10.3 vdc (could read high 13vdc as it is unregulated)
I Got: 20.6 my original block got 20volts
others Got 13.36
Meter set to 200vac
Red lead to pin 6
Black lead to pin 7
Reading should be 36 vac
I Got: 46.9vac my original got 0 volts
Others have Got 32.4 vac
Meter set to 20vac
Red lead to pin 8
Black lead to pin 9
Reading should be 6.3vac
I got: 6.7 vac original got 0 volts
others have Got 5.8 vac
Meter set to 200vac
Red lead to pin 10
Black lead to Pin 12
Reading should be 60.1vac
I got: 78.5 original got 0 volts
others Got 55.7 vac
Meter set to 200vac
Red lead to pin 13
Black lead to pin 15
Reading should be 80 vac
I got: 78 vac original got 0 volts
others Got 55.6 vac
I also verified that with continuity test that all fuses in both blocks where working and in good condition.
I also tryed three differen regulator boards without a load and would get 6 volts on each board no change. Plugged into load with my old game board the board got 5.78 volts to 6 volts
not sure what I should do next? Thanks
