Modified electric actuator for CP1 level control (liquid level control valve, LLCV)
Continued WP #6472 see also entry 34052 

I rediscovered the fact that 3 of 8 of these actuators have different power requirements and are wired differently in the vacuum racks.  Prior to lifting leads to facilitate today's work, I had pulled the nominally applicable fuses.  Later I found that I had blown a fuse in the vacuum rack at an unexpected terminal number and then realized the novel wiring,  Of the three remaining actuators to be modified under WP #6472, two ought to have similar vacuum rack wiring.  I'll inquire with CDS regarding a drawing revision.
