Hello! I am an ag teacher and my students are restoring a 1942 Ford 9N. My students are having a lot of trouble wiring the battery for the 6 volt. We are not looking to convert for show purposes. Does anyone have a video or anything that can help? I have only found a few schematics but we are still having some problems. Anyone have any ideas? I don't want to have to convert it as it will hurt them in the show ring. Thank you.

Start with the essential correct manuals. The I&T FO-4 manual and the 9N/2N SERVICE MANUAL are good to begin with. You can get a free download of the latter at the NTC site, in the 'manuals' forum. OEM FORD electrical systems were 6V/POS GRN setups. Here is what you should have: Front Mount distributor; points set at .015"; 6V square-can coil; Champion H12 or AUTO-LITE 437 sparkplugs gapped at .026"; and the 9N after s/n 12500 and all 2N's used a 1-Wire/3-Brush generator; the round-can cutout; OEM Ballast resistor; OEM Neutral Safety Starter Pushbutton Switch (by shifter); an AMMETER; an Ignition Key Switch; 1-Wire starter with NO solenoid; and a good GP1 6V AG type battery. Verify wiring is correct before turning over and you can polarize generator by arc-sparking the two cutout terminals; BAT & ARM with ha pair of plier handles.

Make certain that you and the students understand that your tractor has a positive ground system. In other words connect the Postive post on the Battery to the ground spot on the tractor. (The Dash) The negative post runs the Electrical system on the tractor. I am not an expert but no one else seems to mention this. And you said your students are having trouble with the Battery hook up.

Yeah, I did mention the OEM setup was 6V/POS GRN if you read my post thoroughly. BUT, it doesn't HAVE to be, it just works best with a positive ground. Some fellas even slap a 12V battery in with no other changes and it will run fine -starter motors don't care if 6V or 12V. Polarize the generator for whatever is used. It's all in the correct wiring/components and having the distributor set right. The OEM diagrams I posted are pretty straight forward.

Hey Guy - haven't seen you around much, how are ya? I concur that JMOR's WIRING PICTOGRAMS are the best document compiled for wiring these N's -easy to follow and you don't need to be an electrician to understand as long as you adhere to 100% and take no shortcuts and/or omit parts/steps. Technically, and I'm not criticizing you, they are not 'wiring schematics'. A schematic uses electronic symbols and drawn as they would be wired. Like this:

Once again, you and your students can get all the information required on these old N's in the original Owner/Operator/Parts/Service Manuals, the I&T FO-4 manuals, and JMOR's wiring pictograms. The MPC's will show exploded views (see picture) and list all the parts and the others will have wiring schematics and diagrams to further assist. All the original MPC's are available for free download at the NTC site. The 39-53 MPC and the I&T FO-4 Manual can be found in new reprinted copies at just about every parts supplier -try nnalert -but prices vary so shop around. Timing the front mount distributor is very critical so start there.

Take photo's of everything on your tractor now, in particular take photo of inside of Distributor where the points are located, at the top of the distributer you will see a Brass bolt that the Coil spring sets on. It is critical that you use a Plastic insulator here so that the brass connector from the points and the Condenser which are connected here do not touch the body of the Distributor.
