G2A 89 I believe wont start, what does this diagnsotic result mean?

[aviator8]

I have a G2A that was given to me. To the best I can tell it is a 89 model, and has had several modifications over the years before i got it, some to the electrical (cut wires, new fuses, etc) This was running fine after i got a new carb, but then just started going, then not going, back and forth after about 2 months use. motor was engaging and firing but off and on, as if it was starving for gas. I got tired of messing with it so it has been parked a year. This week i decided I would fix it........

Dead battery, replaced and verified good voltage

I push the pedal and hear the solenoid click but nothing happens

I tested across the solenoid and was getting 2 volts on the output side when the gas pedal was pressed so i bought a new one

I put in the new solenoid and got the same result.

I get a full 12V on the input side with pedal not engaged, while holding in the pedal i checked the output side and have 2 Volts, which was exactly what i saw in the last solenoid. Now for grins while still holding in the gas I checked the voltage on input and output and have 2V on both sides! What does this mean? Do I have a short? I am not sure where to go to next, I already threw good money away on this solenoid I think, and don't want to just start replacing things until I isolate the real issue.

I have also tried following:
Looking at the wring Diagrams to verify connections and grounds, and it is not easy with all the wires in chases, replacements with non original colors, taped and zipped together end to end, etc.

I removed and cleaned battery terminals, frame ground contact, positive and negative terminal on the starter generator

Checked all fuses

I even tried the screwdriver across the solenoid trick before buying a new one with no change in results. I believe that this did not work because I was not getting 12V at the input side with gas pedal pressed, was only 2V.
