Maybe this will help in the future.
This is what has happened. The DME internal circuit 15 is the 5 volt supply for some sensors. It is the supply for the throttle actuator. This voltage is now battery voltage causing the codes for high voltage as it returns to the DME over the max of 5 volts. Have seen this on a few 4.4l w/ DME 7.2's.

Looks like George goofed on this DME repair or something is shorting this circuit.
