Has anbody else ever converted there sy. to 12 volt chevy round type coil and not use the resitor. I removed the top off the burned up 6 volt coil and removed all the guts and drilled a small hole for my coil wire and then solder a coil wire in and a jumper wire from top of the cap to the point were the connection is made from the points. Be sure to change the condenser to 12 volt condenser. Mine has worked for 3 years now with no problems. Be kind dont bash me hard.

I have an old bad 6V square coil or two, I may rig one up to test.Still 6V and not changing. Maybe a 40-50KV/12V coil??. Buy points & condensers by the bag?? I'm talking about testing & measuring here for fun.However I do have a scope and several other meters.(8N is mostly just noise!) Maybe a 15 or 20 MFD electrolytic from a tube amp (collection)? I've got it! An AB tube amplifer on the primary...., let's see....where's that vibrator from the '54 plymouth..... Seriously I would love to drop in electronic ign. that is 6V and FMD! After hearing a theory about the everpresent 'stutter' being corrected by electronic ingnition. While I am big on staying stock 6V, I love to tinker with hybrid stuff for fun. Or just joke about it.

To each his own.

Just bought an 8n with the setup you have. The tractor has not cranked yet. But after I get it running it will be rewired. The ignition switch has been moved to the dash which makes it easy to get run over while working on the tractor. Most of the wires are routed so they can easily burn through and short. Plan to leave the coil and ditributor the way they are as long as it works. It would be nice to have the coil on the distributor just can't spend the dollars.

Jay..... ....I now know of 8-ways to convert to 12 volts, congratuations. (grin)

Try explaining your conversion technique to the electrically and mechanically challenged.

For those that desire to convert thir N-Tractor to 12 volts, I always recommend a real 12 volt coil. And since there is now a square 12 volt frontmount ignition coil, I definately recommend that way.

And since most distributor capacitors are generally rated at 200 volts, there is no 12 volt capacitor requirement. BUT each ignition coil has a unique capacitor capacitanace requirement in "microfarads". and not all distributor capacitors fit inside the the frontmount distributor.

All-in-all, what ever works for you, BUT I can't really recommend your kludge job, sorry ..... .....respectfully, Dell

I just put a 12 internaly regulated alternator on my 8N can one of you with the knowledge help this farmer out with the wiring? I have a Resister that came with the tractor, ( it was entirely in a box or ten) I dont know where the alt. main wire goes. I made it a Neg ground but from there? thanks fellas im desperate now cause the gardens on m,y ol' ladys do list.

Mike..... .....you don't give me much to go on here.

6 volt 8N's come with 2 very different distributors. The square frontmount distributor coil which uses the infamous "ballast resistor" mounted on the backside of the dashpanel. Or the sidemount distributor which uses a roundcan ignition coil and no ballast resistor.

Then there are 2 different internally regulated 12 volt Delco SI-10 alternators. The seductively simple 1-wire that requires you to goose your just started engine to over 2000 rpms to get it to charge. OR the 3-wire idiot light version that starts charging as soon as you start your engine at 500 rpm idle.

Glad you realized your 12 volt alternator requires NEGATIVE GROUND. And just incase, your starter motor doesn't care, positive or negative ground, it still turns the same direction. HOWEVER your ammeter does care positive or negative, traditionly the ammeter is hooked up so charge into the battery shows plus. Swap the ammeter lead around.

Usually, most 12 volt conversion kits have instructions included, your 10 piece kit didn't come with instructions? I'm shocked. If you don't do it right, you'll never get your engine to turn off once you get it started. (disconnect your coil wire)

There are several 12 volt conversion pages posted, try a search of this great N-Board at the top of the page. 12 volt conversions come in many versions, some of 'em even work. Do it right the first time. Don't hide your question 3 pages back, be brave, post at the top of the #1 page. You'll get better answers faster.

But to answer your specific question, most connect their alternator 12 volt output to the starter solenoid battery terminal because it is eazest..... ...Dell
