Morning
With the new resistor banks in from the night electricians, we set out to test the bombardment on the dummy load. The tests were not very successful as it still wouldn't stabilize at all. We blew some fuses and needed to get replacements for those. Even after taking the circuit down to the scr's and plugging in a space heater, we still didn't get the right voltage. Things weren't looking too good.
Afternoon
Tony figured there must be something wrong with the trigger board to be causing problems this far back in the circuit. We took the amplifier prints up to the 480 panel and started tracing wires. The wires from the 120 to the 480 were fine, but on the actual scr's themselves there was something wrong. The wire from the scr trigger to the driver board was flipped. The negative thyristor was firing when the positive should have been and vice versa. We flipped them around and presto, the thing was pulling like a champ. Tony got all the crap that we'd put in to test out and the bombardment work great. Ordered up some fuses for tuning.
