Good Day: Just bare with me here. On that J2/P2 there are pins DEF and def. DEF are on the outer ring of the connector and DE go to nothing(similar to your strange readings), and F goes to the K1 main contactor, pin X(also similar to your test readings). def on the other hand are located on the inner most portion of the P2 connector and they all 3 traves down to the relay box to connector P5B/J5B gray connector and inside the box they connect to P11/J11 connector pin 1 and from there it goes to the starter motor where a bunch of wires connect to the one stud of the starter mounting bolts forming the B- chassis ground. This is all on FO1 sheet 3 of 6. I'm a bit slow at my age so I stuck the nose into the foldouts.
For your meter, set it on reading resistance and put the leads together, if set to make noise this is what your looking for, 0 resistance and making a noise if you set it on that position. Easily checked if you place one lead on d,(inner most pin on J2) to that ground braid that is supposed to be connected to the DCS. Or any good chassis ground. Should get no resistance, straight shot, chassis ground. Now, if all is in order, you have B+ and B- to the DCS and it should power on.
If not, best to take it inside to a well lit table and start looking inside that very clean DCS as it is not working and hopefully find an issue inside the DCS and they never published anything on the inside of the DCS where things go like a schematic as it was proprietary as they said. Yes, I asked in 2009. There are on circuit board circuit fuses. If everything is NOT in order, check that P11/J11 connection that you have good connection from the J2/P2 pins def to that J11 pin 1, (if no connection time to open the box and see why not)and then if good from the P11 to the starter stud. I hope some very intelligent person changed the starter (common issue) and missed a wire and all will be in order once put back in place.
