Starting Problem

I installed a new starter switch on my 9N and it's not working. It wasn't exactly the same as the original (holes to mount it didn't match up) Modified it so I could mount it and connected cables-nothing happens when I push ignition button. Battery is good-got juice to the switch, but when I connect the negative battery cable post on the switch directly to the post that has the cable to go to the starter, nothing happens. Tried unmounting the switch and pushing up the plunger on rear of switch to manually make contact-nothing. One clue - I had to replace the heavy thick cable from the switch to the starter. Used a smaller diameter battery cable. Anybody know what my problem is? It's driving me crazy cause it's 14 degrees in the barn today.

You can only get the starter solenoid for a 1940 and later 9N from your local New Holland dealer, the aftermarket companies only carry the early one because it also fits other make tractors like Farmalls. Your problem is either a poor ground or the bendix is stuck in the engaged position and jammed in the flywheel teeth, To fix this loosen the starter mounting bolts and put the tractor in high gear and rock the rear wheels back and forth to release it from the flywheel teeth take the starter off and hold the bendix housing (not the end with the pin through) against a bench grinder hard enough to spin the bendix at a high enough rpm to return it to the off position.

Hey! My 2N's not starting at temps in the teens. It started great at 30 degrees. I'll find out if I've cured the problem in the next day or two.
You've jumped around the switch so set that aside for a bit. That advice about putting a heavy cable back on there is good advice. I believe 2 guage is good. I am replacing a 30" long, skinny battery ground cable attached to the dash with a 9" 2ga. ground strap attached to the top of the steering gear housing. The parts book shows a 5 1/2" 2 ga. ground strap but TSC doesn't have anything shorter than the 9". I was losing 1/2 volt or more with the old ground.
If you have start problems you just have to get the wires and cables right. Get the right size, get 'em clean, and get 'em tight. With that done you have a reasonable chance of finding the problem without being confounded by poor connections and bad wires. Get the battery charged up too.
Candianiner posted a procedure yesterday that can put you on the road to starting your tractor if you can use a voltmeter.

Ross,

If I read you post correctly when you say, "Battery is good-got juice to the switch, but when I connect the negative battery cable post on the switch directly to the post that has the cable to go to the starter, nothing happens." Then you are not even getting any sparks when you bypass the starter switch and hook the battery directly to the starter. Correct?!?

That means one of a few things all of which mean you do not have a complete circuit from the battery thru the starter back thru the engine/frame/ground to the other terminal of the battery. Worst case will be bad starter.

But lets check the easy things first. You said, "got juice to the switch" so I hope you mean you have a volt meter or other way of detecting voltage. See if you get voltage from the HOT battery cable to the frame of the starter. If no, then that is your problem (I hope and not more) and you need to try connecting the ground battery cable to the starter mounting bolt and recheck. If yes, there is voltage - i.e. the frame is grounded, then check to see if there is voltage from the battery HOT to the terminal on the starter - that goes to the starter switch. The starter should look like a dead short to the voltmeter so you should see 6V. If not - ouch!

OH yea, do like Tom says, GET rid of that small cable!!!

I could go on and on but would rather see what you find from my description so far.

GOOD LUCK!
Regards,
Larry

For starters,(pun intended) If you have a 6 volt system immediately replace the new wire with a thick cable like you took off. It is required. It is not the voltage but the amperage it has to carry to the starter as to why it is needed. The 12 volt does not require as much amperage and thus can use the thinner cable. Us a 2/0 minimum andlarger if you can get your hands on it.

Check to see if you have a good switch. Try to jumper it and see what happens. Switches are known to go bad and I had a bad one 2 yrs ago right out of the box...

Check your ballast resistor with a VOM,(volt-ohmeter) and see if it is open, if so, replace it.

If these don't work, check back and the experts will be more than glad to help also.

Good luck
Tom-Pa
