Help!!!?

Have an old Hobart portable with a Wisconsin. All the sudden it won't turn over, uses 24v thru the welder as the starter.

Where to start troubleshootin?

Pull the spark plugs, see if there is water in the cylinders. Wait a minute, that engine is air cooled, so that won't work.

Can you crank it by hand? Are there any holes in the block? Does it have oil in the crankcase? Did it make funny noises last time you ran it?

None of the above, I can turn it over too.
This seems electrical

There will be a solenoid in there to switch on the starting current. Look there.
Even if you hear it click when you push start, does not mean it is conducting current to the start winding.

1. Is the battery charged?
2. When you engage the starter, does the solenoid click or no clickee?
3. Does the starter engage but does not have power to turn the engine?

Oh so many questions and so little information.

From what I gather, there is no starter? Just the current thru the welder to act as a motor? I think Ironman (Gerry) has the situation figured out.

That's right , like a lot of Onan generators. There is no separate starter motor,the " solanoid" is simply a heavy push button switch containing solid copper bars that make the contract. I'll be looking into the situation deeper this weekend, as it's my backup portable. Main portable is a Bobcat 250 NT, that has been waiting on a range switch for over a year. COVID issue with their supplier as I understand.

Problem solved !!!!! The batteries were dated 8/20, put a pair or new ones in and she fired right up. Should have not panicked and looked when it happened, and why do these things always happen when your in a hurry 100 miles from the shop?

They happen because you are in a hurry and 100 miles from your shop.

Always good to check the basics first.
