Meter lamps came on, but non responsive otherwise.

An open circuit diode was found, D3, so no 0V GND rail existed.
Easy to find using an ordinary DMM.

A better method of eliminating the voltage drop problem across R10 20 ohm 5W resistor (that feeds +12V to the External Control connector) was suggested by … Read more...
