We left the LVEA around 3:30 after chasing GS13 signals.  EE/CDS drove our sensor cables at the AA & Interface chasses and confirmed we have signals coming out.  We find now that the HI ISI HAM4 model is incorrect according to the wiring (D1000298.)  Except for the expected difference regarding CPS on HAM2 & 3, the models match.  However, the GS13 & L4C wiring is different.  So we have to change the model or change the wiring.   At the moment we have just H2, V2 & H3 sensor on the ISI plugged in.  We'll continue when the wiring/model gets sorted.
