I'm happy you got it working. I hope it still runs in Weld too but I'm sure it should. And if you ignore your time it was a cheap fix too.

So first things first does it run in power setting? And then does it generate power?

The diagram doesn't exactly show 52 connected at the coil however it does show a branch in 51 that one side goes to the Weld/Power switch and the other side goes to S2 after which it is 52. It is possible it is labeled 52 at the coil.This would be essentially the same thing as the branch if 52 goes...

Yes, I would agree with that statement. S2 is a limit switch in the throttle assembly that connects wire 51 via wire 52 to wire 53 in the Power setting of the Weld/Power switch and only if the throttle is also set to Power . At least according to the wiring diagram as I comprehend it.

In the diagram wire #51 comes from the coil to the Weld position of the Weld/Power switch as well as to S2 so that in the Power selection ignition is connected. See in the throttle of the wiring diagram if you haven't already.

Verify S2. In the Weld setting ignition passes via Weld/Power switch only.In the Power setting ignition goes via S2 and the Power/Weld switch. I think it is intended to force the operator to push the throttle to the power setting by cutting the ignition in the Power setting until the throttle is pushed...

Are you disconnecting the wires at the coil to check continuity from the Weld/Power switch to the coil? I ask because I wonder if you are seeing continuity though the coil on wire #51 since it is supposed to be connected to coil (-). I would be looking at S2 (switch 2) which I assume to be in the throttle...
