I am so glad I found this forum. I'm a newbee and the information I've found here is great. I have a 1949 8n that has been sitting for at least 2 years under a shelter. I'm going to try my luck at restoring it. Everything on it is original, no conversions. The tractor was running when it was parked. I drained and cleaned the gas tank. It is still in good shape. I replaced the shut off valve which was gummed up. I installed a new 6V battery. The motor turns over but it would not start. I checked for spark by taking out the spark plug and turning over the motor, no spark. The wiring and plug wires are in bad shape. I am replacing the wiring harness and plug wires along with new spark plugs. Here is my question - should I replace the coil, voltage regulator and the electrical resister? Is there an easy test to check these parts? I am also going to install a distributer rebuild kit. I did check the points and they opening and closing, not burned. Any help is appreciated. Thanks. I will post pictures soon.

Did you clean the points at all? Eaven though they are not burned, they could be dirty, or coroded. I would try cleaning, or replaceing them first and see what happands.

Well hello, shutt24, and a great big welcome to the Tractorforum. You will find plenty of 8n help there. I see Ingersoll444 has already chimed in and I’m sure you know Andy, the owner operator of this board, is a big 8n fan and has experience with restorations.

I will look forward to hearing all about your efforts to get your 8n up and running again. Can’t wait for the pictures.

First let me say, I’m glad to hear that you have tractor where “Everything on it is original, no conversions.” If I were you, I keep it that way as much as possible. I’m told if the electrical connections are kept clean, bright and tight there will be no need to do a “12 volt conversion”, which is usually one of the first things new 8n owners want to do.

I’m not much of a mechanic but if the plug wires are in sad shape that seems a good place to start. You know, of course, to get the plug wires with wire cores not the modern carbon core type. If it were me, I wouldn’t replace the coil, voltage regulator and the electrical resister or any other part until I could confirm that they are bad. Sometimes you can install a problem while replacing parts. You say it was running when parked under a shelter so there is a good chance most of the components are OK.

With a 49 8n you should have a front mount distributor which is easy to remove from the tractor in order to do maintenance on it. I’d clean the points, first by running a stiff paper through them, if that failed to clean them, I might lightly file them.

If you have a good spark after cleaning the points you will have checked the coil, and the electrical resister the easiest and surest way possible.

Checking the voltage regulator probably needs to wait until you have the tractor running. Then check for an increase in voltage across your battery after starting the motor.

Thanks for the replies. I have ordered a wiring harness and plug wires(wire inside). Should be here by Friday and will install this weekend. I'll let you all know what happens.

Welcome shutt24 :friends: let us know what you find out. Like what was said above check the inside of the cap for corrosion and the points for corrosion.

Welcome to the forum! I'm smack dab in the middle of completely rewiring my 48 8n that's in my icon. One thing I'd definitely check is the coil. Two very common things can happen to it. One is if the key was left on with the points closed the coil is gone. Second and what happens most often is the spiral spring on the bottom of the coil either has burnt the tip of the coil off or its just plain not making contact with the brass cup screw underneath it. Fix it by stretching the spring until you have to just slightly push it down to get the bail to lock.

Personally I'd just plain replace the points. They're cheap and it's good insurance if the tractor been sitting for awhile. If'n you have a digital VOM you can measure the coil from the top terminal to the spring and if it's good it should read around 1.5 ohms.

Again, welcome and I hope your tractor gives you as much entertainment as mine has!

Things went pretty well this weekend. I got the wiring harness, plug wires and switch installed. I had to order a terminal block and starter relay this morning. I spoke to the folks at Just8ns and they told me I needed a 3 post terminal block and I have a 2 post. I purchased a new ammeter but it is different then the origninal. The original had a coiled wire on the back that a wire ran through, the new one just has a pos and a neg post. Can someone instruct me on how to connect this. I followed the wiring diagram on the N-series.com website. Also on my new switch it has a black wire and a yellow wire, does it matter which one is run to the 1st post on the terminal block and which is run to the bottom(hot) post? As you can tell I'm not good at electrical, but I'm learning. I'm going to try and post the pics I took this week end.

Here is a rear view. Is there a way to post multiple pics? I haven't searched old posts on this. I'll do that now.

I’ll take a shot at a couple of your questions until the real experts wakeup/thaw out? What little I know about this is from reading. I have no hands on experience.

Cut the wire going through the coil on your old amp meter and connect the end going to ground (engine block or some other big hunk of metal) to the positive pole of your amp meter. Of cause, the other end will attach to the negative pole of your new amp meter. You did say your tractor was in original configuration? Which has positive pole of your battery is connected to ground. If you get this wrong the only thing that will happen is your new amp meter will read backwards and can be corrected by simply reversing the wires. (Don’t throw your old meter away. There may come a day that you or someone else will want to restore it.)

I can’t answer your question about your new switch. Perhaps someone here will wakeup/thaw out? before long that will have the answer, but I think they are going to want to know which switch you are asking about.

Keep the wheels chocked and the transmission out of gear until you are sure all your wiring is correct.

Your asked “Is there a way to post multiple pics?” I’m going to assume you mean multiple pics uploaded to this site in a single post. The answer is no. You can only upload them one at a time on this site so that pretty much limits you to one picture per post.

Great pictures you have posted, “sized” well and everything. No reason to change the way you are doing it.

You can upload more then one picture per post but not using the Browse button. You have to use a server like photobucket and copy the address to each picture and put them in your post. Just like this. This is what you copy from photobucket or if you use some other then you do it like this and where it shows your host.com you put your address in place of it. But it has to be like the picture below with the lettering.

That is a very nice tractor. The potential for a beautiful restoration. It's refreshing to see one so complete and original.

Do you plan on working it on your 50 acres? That old gal is going to look good with a rotary cutter on her back. Hope you keep us updated on your progress.

Unfortunately for me, good 8 N's are very rare in my area. I have gone to see 'for sale' N's and they always seem to missing major key components...and the asking price is just too much. I'm not that frugal, but 3 X's the original $1200. for a tractor that doesn't run is a little pricey.

Regards, Mark

Nice looking tractor you have there. A good starting point for a resto it looks like.


Sorry I cant help with the elect problems. Never been there myself.

I plan to use the tractor on the farm for different things such as cutting the field, working the garden, scraping the driveway and making wildlife food plots. I also have several attachments for it.
We used it a lot in the 80's and early 90's.

I decided to work on the electrical for a while last night and made progress. I finally got my points to fire, and then I got my plugs to fire. I poured a little gas in each cylinder, put the plugs in and cranked it. I have the carb off rebuilding it. The second time it turned over it popped a couple times and then several more times. I should get my other electrical parts and carb kit today.
It's starting to come together. At least I have fire, now I need to get fuel.

I spoke to a friend last night who has a large bead blaster cabinet that I can use. I going to start taking some of the smaller parts over there and start stripping them. I always heard the key to good, lasting paint job is the primer. I guess I'll start my research for the best primer to use.

Welcome to the forum schutt24! I'll be following your progress as well. Sounds like you are doing ok. I wish I was able to help in the electrical stuff, but all I know about electricity is that it hurts every time I fool with it. :dazed:

That is the diagram I am using. I am not for sure on the ignition switch to which color wire to attach to the top left post on the terminal block and which color to attach to the bottom post. There is a black wire and a yellow. It may not matter. Thanks.
