CL-4, CL-5 Cooper regulator control repair

The CL-4 and CL-5 are very good, easy to interface controls, differing mainly in amount of features (reverse power options) and metering options. Best human-machine interface ever presented in a digital control. Connector pinout at bottom of control housing is identical between CL-4 and 5.
