At pin 4 of U1 I am seeing +2.1 volts also at regulator seeing the same thing. Pin 8 is reading fine at +14.5 volts. Checked caps and diodes. Also checked for shorts at U4 and U5. Do you guys or Tim think the regulator is Bunk? :shock:

Can you carefully measure the voltages at the regulator pins? Let us know what you find.

From left to right facing the white lettering on the regulator +1.9, +.6, +2.1.
