5" of snow, now rain all day got me to go in the polebarn and get a task taken care of. Converting my 6volt 8N to 12v so I have a dependable starting tractor this winter.

Don't know why I'd been putting it off. Ive had the kit for months. If I had to do it again,  I could do it in a 3rd the time now.  :) it was actually an enjoyable job.

My first car was a "hand me down "  '63  Volkswagen beetle with a 40 hp gas engine. For the people that remember catalogs and Sears & Roebuk ( sp? ) , you could order complete engines and many other parts from their catalog. Anyway , the car had a 6 volt system and a generator. The car always started , no problems there , however , vehicle inspections were a headache. Between the 6 volts and a generator, instead of an alternator, the headlights just could not meet the minimum brightness needed to pass the inspections . No matter how fast my 16 year old self would rev the little engine while we sat in the inspection bay it would never reach the minimum illumination required . I'd sit in the car staring at the big circular dial with the minimum illumination marked with a big red line .No matter how hard I pushed on the foot throttle and willed the lights to get a little brighter , the indicator hand would just barely approach the minimum. Fortunately , in those days , you could go from inspection station to inspection station till you could find a sympathetic inspector  He  would shake his head , look at me , I'd shrug my shoulders and look at him. He'd look at me  , shake his head again , shrug his shoulders and pass me through. Ah , the joys of youth and poverty! I wish I still had that bug , but I'm happy to have 12 volts!

My tractors are a mixture of six and twelve volt models but all have generators.  I have found that a 6V system will perform as expected when all else is near perfect, meaning good 00 cables with clean connections and generator that will charge a good battery.  In my experience keeping a generator charging is the challenge not the voltage but your 12V system with alternator is a much better system on tractors that operate at full throttle most of the time.  

Jeff, your alternator looks brand new or at least very clean.  My old green tractors will barely spin an alternator fast enough to keep a battery charged especially on parade tractors.

The newer generation 1 wire delco alternators only need 600 rpm to charge. I bought the entire kit from yesterdays tractor a few months ago for $150.  Alternator, brackets, new wire harness and resister, which I did not use because I switched out the coil with a 12v one I got from @Harold .  

Usually when I need a tractor in the winter here in Michigan it's cucu co-weld and this should help.

That's the same kit we put on our 8N this fall.  Makes a big difference  8) 8) 8)

Nice job.  Personally I prefer my tractors not have spark plugs, but I love the wall coverings behind the tractor!!

.....and power steering.

I did a lot of work with my 8N though.  I sold it to a girl with an even older manure spreader behind it.  As far as I know, she's still using it.

Jeff you'll hafta be a little more judicious with the choke this winter. The 8N will flood much quicker spinning over faster.

Those 12V conversions on those 8N's really make a nice set up. I have changed a bunch of 6 volt tractors over to 12V in the last forty plus years. 

Jeff

I've got an issue I have to figure out. I'm thinking it may be a starter button. The solenoid keeps kicking in and out if the engine fails to fire and the key is on. It looks like engine run on when it does it. I can't imagine how ekse it could stay energized.

Sounds like it my be the starter bendix. A weaker bendix will show up quicker when you are spinning it over faster with 12 volts as opposed to 6 volts. Can you get a video with sound, it would be easier to tell if that's it.

It was a wire wrong on the key switch.  So I get that right, put the tools away, and now it spits and sputters when you try to give it throttle. Starts instantly.

Remember your 3 legged stool: spark, fuel, compression!

They have to be the right amount and right time to work, on any internal spark combustion engine engine.
Diesel is only slightly different.

It ran fine until now. Im wondering if the 12v ate the points. I swithed out the 6v coil for a 12v system so I didnt have to use the resistor. Perhaps the poins and condenser failed?

It's possible, but I'm not leaning that direction. 

How long of time between 6V run and 12V run? If any time more than 6mo, I'd be fuel suspect, starting right up or not.

What's your current compression numbers? I've seen good start and run on 120#, just not GREAT power. 

My first vehicle, 74 IH pickup and being a teenager, I hot-rodded that thing. It's a tractor that's interstate legal    :-X
Anyway, its point ignition never gave me BIG problems, but a few. Check the integrity and gap. Condensers are like extremely short term, high voltage (very low amperage) batteries. Replace both if in doubt. ~20 bucks for both at most NAPA. I'm not trying to promote them, that's just where I cut teeth on selling parts, I sold & found LOTS of tractor parts there. 

I'm thinking carburetor internal problem, but I'm not there, hard to tell.

Is that an early 8n with front mount dist or later with side mount. If it is side mount, is da round can coil you installed internally resisted or not. I'm not positive but pretty sure all the 12 volt top mount coils are externally resisted.

Tacotodd

Yeah, if you run no-resistor coil, you'll need a resistor wire in your system. The coils I sold told you on the coil themselves if they were or not. 

The more I think on it with my personal experience, fuel related. 

Like a chainsaw, filter, lines. Most likely something basic and small. The stuff that drives you crazy!

How's your voltage resistance on the wires?
Trying harder everyday.

Jeff

It is a very old coil. Most likely, non resisted. Fuel is good. Changed the condenser,  the points look okay. It us now backfiring if I try to throttle up. Starts instantly , sits and idles nice.

My old 12 volt Ford cars had resistors.  They cranked on 12v and ran (through the resistor) on 6v.  If it cranked and then died immediately when you released the key, you knew that the resistor was open.

Use a 12V internal resistor coil and be done with that part, it won't hurt.
