Tempest Power Brick Pumping 20 Amps of 36VAC...NOT! - Now no +15 @ Tempest PCB
As the title states, I have a Tempest brick that is pumping out a whopping 20A on the 36VAC line. Why???
Fully rebuilt; big blue, fuses and holder, rectifier.
Was working fine until I decided to plug a Major Havoc board (w/adapter) into it to test. MH played blind. Switched back to Tempest and noticed no 15V or 22V at the PCB. Fuses F4 and F5 blown. Replaced, blown again. Connectors are new and test fine. Finally discover with my trusty Fluke that the 18VAC coming into F4 and F5 is coming in at 20 Amps!
Googling led to possible rectifier. It's new, but whatever. Replaced it with another, still got 20A at F4/F5.
I know it's near impossible that the transformer/windings are shot, but that's all I can come up with at this point. WTF...
