Anybody have an opinion on the pointless ignition for the N's? I have a 2n that is difficult to keep points operating correctly.
I set them to the proper gap and the tractor runs great. I let the tractor sit for a few weeks and it is hard starting and runs rough.
Once I set the gap again it is fine. I think the
points are actually slipping. I torque the darn things as tight as I dare and they still seem to slip. I even roughed up the mating surfaces to
reduce the problem, but alas, they still slip!
I thought an electronic setup would solve this problem. Thanks, Steve Pesta

I don't know how the system works out on a front mount distributor but it was the second best thing I ever did for my side mount. The Dowden footfeed has been the best. I bought the Genessee outfit. They have tech service second to none.

I, too went to the dreaded Electronic Ignition a couple of years back. It has increased the power, decreased the crank-time b4 starting, and is generally better than free beer! I was having to constantly get off and f*** with the points, usualy died in the most inopportune times! BUT: I saved the old stuffs so I could switch it back if it ever cocks up, which happens on the weekends when nothing is open. So far, it has been running fine..I highly recommend it, which is against my Traditionalist Attitude!

I put in Genesee"s electronic ignition 1 1/2 years ago. And havn"t touched it since. I have a front mount dist. and what a pain it is to adjust. No more points! better spark, starts on one click. I ain"t going back. Just my 2 cents.

I wasted some money on the electronic breakerless module when I did the 12-volt conversion on my 9N front distributor engine. I also decided to buy a 12-volt coil so I wouldn't have to add an extra wire and a resistor to run the ignition module at 12 volts and still have 6-volts to the coil.

All that money and it worked for a total of about one hour before it fried my new 12-volt coil. So I tried the original 6-volt coil with a resistor and that coil was also fried within a few hours.

Now I have a new set of points, condenser, and a new 12-volt coil. It's been in there working fine for a couple of months. The $100 electronic module is nailed to the wall in my shop as a reminder.

Check your gaskets on a front mount distributor, mine were missing when I got it. New gaskets will go a long ways towards keeping everything inside the dist clean and dry.

I have to add my 2 cents worth here... my 1941 9n has points etc. and starts easily even when it is well below 0 degrees.... when everything (all elctrical contacts incuding the distributor) is clean, starting and running is no problem... I suggest that you clean everything, use a light coat of dielectric grease, and use bluestreak ignition parts. There is a list of part numbers in the archives.

Electronic ignition does work, but the cost out weighs the benefits when all it should take is a little elbow grease and maintenance.

Best of luck and happy holidays

SHHHHH HHHHH don"t tell"em "bout dielectric grease. Best thing to happen for ingnition systems. A good dab on both ends of the plug and coil wire will seal out moisture. when it first came out it wuz $30.00 fer a OZ. Now you kin git a 3 OZ. tube fer $5.00 at yer parts store permatex # 22058 and 3 oz will go a long ways.
You did not here me say this, trade secret ya know.

A new screw might well solve that problem. I understand that one screw holding down the points wears and won"t hold. Length is important so it doesn"t poke down and interfere with the weights. I believe that is the 355047-S 8-32 x .19" Fillister Hd. screw and lock washer. It does have a lock washer, right?

Or the hole in the plate may be worn. You can replace the plate. Try CNH for the screw or cut an 8-32 to .19" and use it.

But then, some times a guy just believes electronic ignition is $exy so if you think that then disregard the stuff about the screw.

Steve..... ....how about a $.50c solution to yer slippin' points? Replace yer short #8-32x3/16 points screw with a NEW p/n 355047-S7 screw. Also available at your Ford automobile parts store.

Heres the deal, yer soft plated screw gitts "invisable" wear that prevents it from holding tight in yer steel mounting plate. Don't use the most commonally available #8-32x1/4 screw as it is too long and will catch yer centrifical advance weights underneath the points plate.

I can replace a lotta points and screws for the price of an electronics ignition kit. 'course I don't gitt the braggin' rights eather. Remember the frontmount electronics ignition kit is not a "drop-inn" replacement. And it won't work on the 3-volts that the "infamous ballast resistor" supplies to the top terminal of the squarecan ignition coil. And the squarecan ignition coil pukes its insulative tar gutts with straight 6-volts. (too many amps overheat the coil)

BIGG TIPP: polish yer ignition points contacts by squeezing a dollarbill between the contacts. This is more better than filing/scrapeing the invisable deposits that occure from setting a long time between usage. Its just a natural thing and you can't prevent it, its called "oxidation" and is INVISABLE..... ....Dell, yer self-appointed sparkie-meister

Yes and no. Yes.. e-ignition may bypass the problem concerning poor maintenance, and points...

On the down side.. if you are 6v positive ground.. the electrical system really needs to be in 100% condition... or the module won't fire.. Barely enough juice there for the equipment to run as it is. Also.. if your distribuitor has excessive wear int he bushings.. or weights.. those will need to be addressed seperately.

In the end.. it's your money.. but.. I find it simpler just to correctly maintain your points.

I see dozens of posts here every month about people having problem with points.. it amazes me. Generally it comes down to electrical issues and cleanliness.

My 8n has not had a new set of points in 5 years.. I do dress the old points and reset the gap about once a year... And heck.. even with a good ignition hone.. 'dressed' points aren't 100%.. yet my units run fine. I do this on my other tractors as well... gets a yearly dressing ont he points.. and go. I can't remember the last time I changed a set of points.. but it is generally.. only when I initially buy the tractor and tune it up.

Gotta observe clean handling with points.. No dirty feeler gauges.. and don't use excessive grease on the rubbing block.

I clean all my ignition tools in spray carb / brake cleaner.. -0- residue.

If your points are slipping.. look at the screw..

Is there such thing as a magneto for 2n, etc or is this a myth? Farmall cub and A tell me I would like to find one. Thanks

Dave..... ....yes, there was a magneto for the 2N, p/n 2N-12500-A assy, also requires a right-angle drive assy p/n 2N-12600 assy. The I&T FO-4 lists it as a Fairbank-Morse FM-J4B73. Installed for some 1942-43 2N tractors because of WW2 shortages. Most WW2 2N tractors were re-converted to battery starters and regular distributors and rubber ag-bar tires when supplies became re-prioritized to raise agricultural goods to feed solders and sailors.

Some N-Engines with magnetos were sold as auxillary power units to pump irrigation wells, oil wells, railroad refridgeration cars, hay-balers. But these are NOT common.

Many inexperienced neubies think their squarecan ignition coil 4-nipple crabcap frontmount distributor is a magneto 'cuz it don't look like their familiar 5-nipple distributor with roundcan ignition coil..... ...respectfully, Dell

As danH said.. mags were used on front mount war time models. i don't see why you couldn't find one.. if you needed one.. but.. as Danh pointed out.. they do require maintenance too..

2n ford used a mag during ww2.Mags were on hand crank tractors that didnt have a battery or starter.Mags cost a lot to fix.25.00 for points or condenser 85.00 for a coil. caps and rotors are pricey.Farmall used mags or distributor-coil ignitions.
