This is supposedly the factory 6 volt positive ground system.



That thing physically located in real life, above the "manually actuated starter switch" must be the "cutout relay" associated with the 6V generator and therefore not needed for the converted system which uses an internally regulated 1-wire GM alternator.


Below is a schematic for a 12 volt negative ground converted system. Not the one I bought, because obviously it's a different alternator.

And marker lamp? WTF?


This below is all that came with the conversion kit.



I have no freakin starter solenoid.

That's just a generic starter solenoid... $20 and you now have one. Available everywhere. BUT WAIT! THERE'S MORE!!!!

That would require adding a push button switch to the dash and finding a place to mount the solenoid. I don't need a solenoid because that big manual switch is literally built into the transmission casting.

It needs an ECM.

BTW this 6 volt system was still working when I yanked it apart... Battery voltage would be around 7 volts when it was running.

That sheet you posted shows which wire off the heavy switch to use for the solenoid.

The starter DOES turn the same direction regardless of polarity. I just checked it both ways, using the old 6 volt battery.



Weird.

Weird.

It's because the current goes through both the armature and field coils (series wound motor.) Swapping the external polarity doesn't change the relationship internally, as the polarity of the field and armature both reverse as well. You can rotate the backplate 90 degreees on some starters, which will flip the armature's polarity and reverse the spin.

That's a big ass resistor. Cuts 12v down to 6v

 

[krelithous]

it needs an EGR valve

stop that he will have a def tank installed on it before we know it

Not that big. Not if a marker light and a 1.6 ohm resistor double (or close to it) the resistance in that circuit.

BTW @Duck , make sure you use an incandescent marker. LEDs are different resistance.

WTF is this marker light? Ain't no lights on this tractor except the ones on the fenders.

I used the schematic that I posted a photo of. I used the old 6 volt coil because there was no part number on the 12 volt one. Used the additional resistor and it shows 1.85 volts on the top of the coil with the key on. No idea why it's so low.

On that schematic where it shows the solenoid, it shows the battery cable and the wire to the ammeter negative (or the one on the right) sharing a post so I just did that on the supply side of the manual ignition switch.

I replaced the battery and starter cables too. Screw those old crusty ones.

Additional resistor? The more resistance the lower the voltage. That's what resistors are for

I don't understand this coil stuff.

Like why do you need to lower the input voltage to almost nothing if your purpose is to make a high voltage for spark plugs?

I don't know. For a coil you need high voltage but not a lot of current. If you didn't lower the voltage the coil would maybe be way to big, expensive and burn up points and caps too much. I'm sure there's a good reason.

a farmer may not have had a timing light. but a simple light bulb set up would have done the job, as the light bulb would have flashed at firing.

Funny!!! You can't use a light bulb to time an engine!! Like what? A 100 watt light bulb from the kitchen? How's that going to fire? With 110 volt? With a 2 watt light bulb from a flash light? Where you getting this 12 volt bulb from? There's a reason a strobe light is used. Because it turns on and turns off very very fast. If you used ANY kind of light bulb it would just stay on. It would never have a chance to shut off completely. It's called persistence.

a simple light bulb, using a 12v socket, much like a tail light.......

it will "strobe" on the firing of number one cylinder....

obviously, as smart as you are or claim to be, you thought you'd discount what i had suggested, as even @Duck (and maybe a few other gear heads) would have known how this could be done.....

you may now go back to your desk jockey's job....

Ha ha ha ha ha. No, it doesn't work.

A strobe light shuts off in just a couple of milliseconds. A millisecond is 1/1000th of a second. That's why they are used. A light bulb stays lit for probably a whole second as the filament fades out.

Maybe there's a Youtube video of some farmer doing it. Until then

this CAN BE DONE with a 12v light bulb/socket......just need alligator clips at BOTH ends.....

obviously, you don;t know much of what you speak...nor do you remember i had said a few times,
back in my earlier years, i used to turn wrenches for a living.....

buh...byeeeeee
