One of the boards is reading 190V on the B+ with the HOT removed. Since the HOT blows immediately, the overload protection kicks in and I can't get a proper reading on the B+ or the low voltage circuits. So I removed the HOT and it seems excessively high. I'm curious if the B+ would be lower if the HOT were installed and working correctly?
I read 107V off of another board that's working for the B+ although I've seen on forums that Polos should be 138V B+. The schematic shows 171V for the "Vb" & "Vc" and 105V for the "Va". There is a "Switch Control Board" that Vb and Vc go into and come out "Vh". Vh and Va both trace to the B+ supply, but I have no idea whether the Va or the Vh is supposed to be the B+ Voltage or what in that "Switch Control Board" is supposed to be doing

If it's fine to test the B+ without a working HOT, which I'm thinking it is, then what would cause the B+ to be so high? The voltage from the bridge rectifier seems to be ok (ranging from 162 to 170 on the boards I've tested).
I also want to note that the Polostar schematic seems to be closer to what I have than the Polo/2 15/25 schematic that I'm using, for example my boards all use "D20" but it's NC on the Polo/2 15/25 schematic. It is shown on the Polostar schematic.
