That is on diode scale, correct?

That is on diode scale, correct? Yes. My DMM display shows a Diode symbol ![]() |

Well your going to love this next one (meaning, your going to hate it). Back to the function board which is the long board with all the ribbon cables attached to it that I had you testing on earlier. Remove the 3rd and forth ribbon cable on top from the front. Right under the forth cable connector you will see C671. It is a tiny surface mount device. You have to remove it. Hopefully you bought 2 irons when you went to Radio Shack. 1 iron on each side of the cap and it should come right off. Just try not to melt the plastic connector above it. Let me know how you make out.

Ok, DMM on diode scale and test across PRY and MG again.

With C671 removed, receiver unplugged, on CB510 MG to PRY = 0.027 both ways.

Pull the ribbon cable out of CB510 and then retest PRY to MG on the back of CB510.

I still get 0.027 V both ways.

I hate to be the bearer of bad news but that reading is not a good sign. At this point I would say you can try disconnecting everything from that function board, harnesses, boards and wires so it has nothing connected to it and then test the PRY to MG again. The black harness soldered to the middle of it goes back and disconnects from the regulator board. Let me know what you get then.
