Unable to replace PCL Kapton PCBs with FCT Kapton PCBs. 
FCT Kapton PCBs exhibited either a high resistance short
(15v/50uA) or expecte diode response as voltage increased
from zero until ~20-30V when leakage curent abruptly increased
to CAN N1419B OVC limit (curremtly 50uA). Return FCT Kapton PCBs
to Edinburgh for continuity/short tests in the automated tester
in the electronics workshop.
