It drops out then slowly builds back up within 5-10 seconds.

I tend to agree that you have a generator issue. Especially since the ATS was replaced and the behavior did not change. I would disconnect the gen leads at the ATS and measure the voltage behavior on the disconnected leads. That will take
The ATS out of the equation. If the voltage is varying at the disconnect leads, then measure at the junction box located at the gennie

Tested at junction box- 120.3,120.5
Made connections moved to ATS
Tested at ATS Genny wires only 120.4,120.3

Hooked wires back into ATS fired genny measured at lugs
120, 119.3
Clunk volts keep dropping until 65,- 70 then clunk and they build again, until ATS is satisfied and it opens again...repeats....

If it did not drop out at junction box then there is issue betyween there and the transfer switch.
Do you have an enrgy management system?

Sir, I have no idea how there could be issue. I got same voltage at junction box off genny as stand alone then hooked wires up at junction box and got same voltage at ends that go into Transfer switch before hooking into switch, then hooked into ATS. AtS opens with correct voltage then voltage drops quickly and switch cuts out and volts build again and switch opens again this continues back and forth.

I’m not understanding how I would have issue between junction box and switch when I tested as stated above and had correct voltage?

I called Progressive Dynamics and asked for another switch which they are sending to me tomorrow. I have to assume this will happen again, so is there any chance the genny feels load and cant sustain 120 per Hot lines?

If it directly between the two it is possible that there is a bad wire.
You could try testing the wires. If flexible conduit is metallic, take wires loose from genset and connect them to the metal portion of the conduit. Go to transfer switch end, measure resistance on each conductor to the metal portio. All wires should read the same.
Energy management system?

Conduit is plastic not metallic. I could run to Lowes and buy 20foot and run new wire is suppose but a lot of money for testing approach.

Before getting new wire, do a load test with short wire to see if genset will hold. Carefully wire a female cord body onto the genset output. Plug some device into it and see what happens.
You could test conductivity by using vehicle frame.

Just so I’m clear. Nip wife’s hair dryer end off. Direct hot to gender wire and other to ground off frame. Ok Bud.
