Ok I got big AC signal on pin 2 of T-605 with the isolation tranny hooked up and scoped and the only AC signal on the other side was small on 10 & 11 so does that whole other side get rectified for each pair of windings. 5&6 / 7,8(ct)9 and 10 &11 ?
So I should get DC at all of those rectifiers right and the ground reference would be the cold gnd or pins 3 & 4 of connector 641. This whole thing sounds like an open ground because the whole supply at CN-641 has no voltage at all.
