1952 8N 6V system has ammeter disconnected. I bought a new one but the old one has no wires going to it.
underneath it there is a junction where 3 wures connect to each other.
I loosened the connection and took the wires off and tried each one to ammeter and nothing.
Tractor never stallled when i seperated these 3 wires. and the ammeter never worked so i returned the wires back and now don't know how to get it going.
The tractor is running smooth now that i changed the points as DELL The sparkie expert guided to me to do but now ammeter wont work.
Can someone help me please?

River....to connect your amp gage in line,Run a #12 wire from the solenoid post that has your big neg. batterey cable attached up to the inside post on the amp gage.Then run a wire from the outside post down to the bottom post on your terminal block.Connected on this post you should have a wire that comes from the BATT connection on the voltage reg.You should also have one of your ign. swx. wires connected to this post, for a total of three wires.If you have lights,the feed wire to the light swx. should also be connected to this post for a total of four wires. Hope this helps....don b

RiverBend. I also am new to 8N's, and come to the site to learn. I love it, and learn alot. That said, some of the guys do throw some strong comments in their notes. Made me feel pretty angry a couple of times. Ignore the hard words, and dig into the archives. Almost all questions have been answered a couple of times different was. I swapped out the wire harness, 25 dollars or so. I did reverse one wire, so keep an eye out if you make the swap. Old wires are just trouble in the long run. Keep coming back to the site, it's the best I have seen. Good luck.

Thanks for the advice...
This is a great site .
sometimes these guys can be a bit harsh, but I guess begger's can't be choosers when it comes to free advice.
I know they have great advice, just not the skills to explain it in a decent manner sometimes.
I usually try to search the archives aswell as not to keep asking dumb questions.
But when you are just leaarning what are you supposed to do?
Have yourself a great day andd enjoy your 8N.

This simple diagram clearly shows how the ammeter is to be connected between the "hot" stud on the starter solenoid, and the terminal block.

Hey guys ...
lighten up. slow down on the comments like"deer in the headlights and squirells on the road".
As i said before the wiring is completely been butchered so the wire diagram is not helping.
I was not trying to offend by waiting for more responses so no need to get all sensitive about it.
Just thought I'd keep on listening. Thats how I learn. If the wiring was stock the manual would help but as said it s not so it s useless at this point.
I thought people come here for help, not to be made to feel like idiots for asking? Iam young and poor and cant afford help nor have someone to help.
I'm trying to earn a living for a family and just needed some help.
Sorry if you were offended.

We can all lighten up a bit. Nothing was meant to offend you, just us chatting and waiting on you to come back and tell us if you got it yet. We'll be here 'till you do. Deer in headlights is what I get when I try to explain computer use to computer user, don't mean they're dumb, just that I need to explain it differently. Squirrel in road dunno which way to go. We're not calling you names behind your back, it would be much more fun to do that right to your face (G)! Now let's fix that tractor...

Thanks Guys!
This forum is really needed by guys like me and we rely on guys like you.
Your tips are great . Last night i got my tractor running like a top thanks to all the replies in the last 5 days fromm everyone. turned out to be a points replacement with new condensor.
i would still be down and out if it weren't for the people like you guys who helped me.
I will do the work on the ammeter and get back to you with the results.
Again THANKS for all the help!

SouNder is right, you should be in the manual, but as an aside, some folks are not schematicly enabled. An ammeter is designed to carry all of the current flowing between (in this case) the genny and the battery. If you can locate the big red wire that connects the output of the genny to the battery, you have located the wire that charges the battery. Now, imagine cutting that wire and putting one end to the ammeter post 1 and the other end to the ammeter post 2 to route all the charging current through the ammeter. That way, the ammeter can meter the current flowing through that circuit. That is how to wire an ammeter.

Now your tractor is certainly not wired like the manual shows it, but the manual will give the idea behind it all. Most likely, in its 50 odd years, it has been miswired and abused beyond regognition. One of the best things you can do is strip all the wiring off the old beast and rewire it from scratch, or buy a new wiring harness. In either case, that will put it back in line with the manual and you will be an expert on 8N wiring, and no more wiring problems!

Thanks.. as you said my wiring looks like every shde tree mechanic attempted to rewire it at some point in time.
That said, i will re do a harness from scratch eventually but for now just want to get ammeter going.
thanks for the tips! i'll try tonight.

Just toadd.. once you do that wire / cut.. make sure all the loads like ignition and lamps are on the side of the ammeter that the regulator BAt wire is connected to.. not the battery side.. otherwise you are shooting your net charge / discharge metering system in the foot..

Easy... look in your manual for the wire diagram.

Tip.. the ammeter is suposed to be wires with all loads and the genny on one side, and the battery on the other.

trace your wiring and look in your manual for the wire diagram.

If you can't read a wire daigram as simple as the one used on an N.. I don't think more replies are gonna help.. i think you need to go enlist someone to read it for you and help you hookup the 3-4 wires that the charge and battery ignition use out of that harness.

Even without a diagram that you state you can't read.. i already told you the easy way to wire it... All loads and bat line from the regulator to one post on the ammeter... the other post of the ammeter to the battery..

IE.. the key switch will pickup power from one side of the ammeter. the send it to the ignition coil.. if this is a front mount, that line would hit the ballast resistor and from the other side of the BR hit the ignition coil.

wire from interlocked starter switch to small in-pointing terminal on the 3 terminal solenoid is isolated from the charging/ignition wiring.

( battery + to frame as it was OEM. battery - to start solenoid. Last terminal on solenoid to copper transfer bar to starter lug.

Lamps would / should also pickup power fromthe same place as the key switch.

Only other wireing there is is for the generator / regulator.. and the is just ground ( obvious ), field and arm/gen .. ARM/gen is on the back end of the generator.. field and ground on the outter barrel.. field is the one that has an insulator grommet.

The n is probably the easiest tractor there is to wire... .. except for maybee one with a magneto and no other electrics.

Just 3 or optionally 4 circuits:

starting
ignition
charging
lamps

It don't get any easier than that.. I pretty much just gave you point to point wireing for every wire on the N

Unfortunately.. the 2 best things i could tell him were RTFM.. or the line by line directions to do it.. With his response of just waiting for more responses.. I'm not sure what he was fishing for.. I doubt he was gonna get more basic advice... that exactly point to point how to do it.. etc.

Oh well.. yeah.. kinda squirell in the middle of the road thing i guess.

He'll get it done, and then he'll be able to pass it on with a whole new perspective. Give it time to work.
