If I follow you correctly then yes, I didn't measure it at turn on but I measured it right after it shut down and there was almost 150 volts and dropping, like the capacitors were discharging, I took that to mean the Power Supply was turning on. .
I had the ribbon cable to SC-1 disconnected during this time. With SC-1 completely disconnected I get 6 blinks of the power light.

When I plugged the connector back into SC1 or whatever number it is I get a nice big arc like it's discharging across a short and voltage drops to zero, this is with the set unplugged, just residual charge.
With SC-1 plugged in the cooling fans power up at a high speed, with it unplugged they spin at a normal quiet speed, like maybe they're tying to cope with an overload on the PS?
