I am working on a power issue with my TAF. Here is what I know so far:
J101-1 and J101-2 show 9V AC.
DC testing on BR2 (following http://www.pinwiki.com/wiki/index.php?title=Williams_WPC#The_.22Replace_BR2_and_C5_Mantra.22) shows 11.3v which I believe is an issue. I recently replaced BR2 and BR3 as I was getting random resets in the game and this was the what a local tech suggested.
The tech suggested I also test AC voltage on the BR2 but I've tried a few combinations of testing and get crazy readings (as if it is DC voltage) on the AC test. Do I need to do this or is the wrong DC voltage testing an indication enough of an issue?
The tech suggested that the LM323K is probably the issue but I wanted to see if there was some confirmation.
I already bench tested the BRs and got valid enough readings on all of them. I did not test the large capacitors as I wasn't sure exactly how to test those.
