1966 JD RF 110 hydraulic

I would check the cheaper stuff first, (if you haven't already). Could be as simple as the keyswitch. I'd check battery, solenoid, voltage regulator. Also the starter/generator can be rebuilt cheap and relatively easy with a kit.

My 112 did that yesterday. Bad connection at the starter/generator.

Yeah I did the light check and key, solenoid, voltage regulator and new batterie is getting all juice to it so I guys it's starter. I have seen a view cheap ones on line just worried how long those work. But probably worth a try.

Bad connection could be the problem too. I haven't dug into it yet and when I was trying to start it. The wire at the starter was sparking and smoking. So I tighten that down and could probably use a new wires.

So I went and tighten the wire to the starter a couple more turns and fired right up! It likes to smoke at first but settles out after it runs for a few. Needs a good tune up and the back right side needs a rear seal fix and hope it's not to hard to fix but hope to tackle that soon. Thanks for all the help guys.
