After testing the AR-II board on my Battlezone all test points show about 1/2 of what they should in AC and DC.
So then I tested a few points on the Atari power supply and I am also getting about 1/2 of what the readout should be.
F4 and F5 read 18vac instead of 36
F6 was correct at 6.1
I tested the pins on J5 and they are off also.
What would cause this low voltage? The bridge or C1?
I know the transformers are rarely the problem.
The power cord looks good and I am getting 122vac
Thanks
