NOTE: COIL PS is a 100 A supply, thus actual COIL current is 0.5x COIL set point.
Changed the FEBIAD connector blocks to have copper tubes exit below the block. Extended ANODE wire to allow it to be wrapped around Cu-tubes and keep it further away from the GE lines.

A leak was observed on the left coil conductor again. After inspecting the service cap, it was found that there was no water flow going through the left coil line due to differences in routing between the TM2 and the Test Stand source tray. A new coil line will be made and the water and electrical connections on the service cap will be reconfigured. |
