'49 9N not starting

[Tfarr]

'49 9N
Died while running
Acts like the battery is completely dead.
New battery
New Solenoid
Will start and run if the solenoid is jumped.
Starter button is a rod not wires.

Do you mean a 39 9N or a 49 8N?
Explain starter button is a rod not wires?

Jumping a solenoid and it keeps running would lend me to think you are pretty much narrowed down to a dirty connection bad solenoid or whatever the rod thingy is.

I was told it is a '49 9N, so I am not sure.

I was told the button you push to start the tractor would have wires which may need to be checked. I took the button off and it was a rod not wires.

I take it you mean the rod at the bottom of this button. If so that Rod disables you from starting the tractor When the tranny is in gear. Needs to be in neutral. If you look at the side of that button there’s a small screw. A wire needs to be attached to that screw and back to you solenoid. If the tractor is in neutral you’re allowed to press the button therefor grounding the solenoid and spinning the starter

BTW The above is for an 8N.

Following thread has a nice write up about a 9N starter switch and the mechanics around it.

You either have a 49 8N or a 39 9N.

The very first thing you need to do is figure out what tractor you have. It will make troubleshooting and buying parts a lot easier.

2 and 9N?s did not come from the factory with solenoids. They all had mechanical starter switches. When you press the starter switch, it pushes a piece of linkage into the switch which manually closes the contacts and completes the circuit. Unlike a solenoid which electrically closes the contacts and completes the circuit.

Does your tractor have a three or four speed transmission? That will tell us if you have a 9N or 8N. Also can you post a picture of your
solenoid?

I will post a pick when I get home. I has a three speed.

It has a mechanical starter switch. I wonder if they added the solenoid later. It is new.
I will take pictures when I get home.

Sounds like you have a 9N (3 speed trans) with a 1948 8N engine in it. Not a problem and not the first time it's been done. You picture is a
started switch and not a solenoid. The switches go bad. If you need to replace it get a stater switch for a later 9N or 2N. The early 9N
switches wit on the dash and will not work for your tractor.

Thank you for your help.

Just to clarify the silver round object with wires is a starter switch? That is what I am jumping to get it to start (putting a screwdriver across the posts).

Is the button with the rod obsolete with the engine change to a newer year?

" Just to clarify the silver round object with wires is a starter switch?"

Yes. It's not a solenoid.

" Is the button with the rod obsolete with the engine change to a newer year?"

Well, if you want to start the tractor from now on by jumping the starter switch with a screwdriver you could forget about the push button..........

Did you miss my first reply to you? I said " When you press the starter switch, it pushes a piece of linkage into the switch which manually closes the contacts and completes the circuit. Unlike a solenoid which electrically closes the contacts and completes the circuit. "

No the button and rod should contact the back of the starter switch. Those switches do go bad. Remove it and test it.

Your start mechanism should have all of the parts in this photo:

The Ford 9N Tractor was produced from 1939 thru late 1942. It then became the 2N model with a few changes. The 2N was produced from 1942 thru mid 1947. The 9N and 2N used a 3-speed transmission with draft control only hydraulics. The 8N went to a 4-speed tranny with POSITION CONTROL added to the hydraulics. A little lever under the RH side of seat is the setting device. ALL 9N and 2N models use the "9N" prefix in their engine block serial numbers preceded and ending with a star symbol. Go to John Smiths site to learn more -LINK below. Also, get the essential manuals to better understand your tractor and the parts it has. All 9N, 2N, and early 8Ns have the front mount distributor with and originally the 6-volt/positive ground electrical system. Many N's have been converted to 12-volts. What do you have? What is important is you know how to deal with the front mount distributor and however your electrical system is now set up as. New batteries can be junk out of the box. Simply charging it does not make it 'good'. Get it tested -your trusty local starter/alternator shop has the special bench test equipment to test it with. The battery must sustain a charge under load to crank the engine over with especially when temps dip below freezing. Bargain house batteries have poor lifespans -2 years on average. Invest in a decent brand like DEKA, INTERSTATE, or EXIDE. 9N and 2N models do not use a solenoid on the starter, but, as Bruce pointed out, you are confusing the solenoid with the starter button -two different animals. Get the manuals, get a copy of Bruce's 75 Tips -just click on it and download it to your hard drive and print it out for reference. The next step is to verify the wiring. You can go thru it while your shop is testing the battery. Do an internet search for WIRING PICTOGRAMS by JMOR or go to the other Ford N Tractor site. Find the system you have and verify it is correct with NO deviations and you can't go wrong. Don't just start replacing parts without knowing if they are good or bad. Start with the basics -manuals and documents, battery test, and wiring verification, and you just might find the true root cause.
