12 volt conversion

[Anonymous-0]

Not too sure how the 12 volt conversion works..Do you need the reducer when you have a 12 volt coil? Can you bypass the reducer and wire differently? Any wire diagrams out there? I just bought the tractor which has been converted and cant figure the crazy wiring the previous owner set up...THANKS

 

[souNdguy]

hundreds of diagrams out there, just for the searching.

so.. what you got for a machine?

boeing 747? cat d8 dozer?

ford tractor of some sort?

if an N.. is it a side mount or front mount distrib.

need those answers before we can give you a detailed answer.

remember.. we don't charge by the word and we aren't mind readers.

the more info YOU provide, the better the info WE provide.

I had the same problem when first getting my 12 volt 8N. Wiring was a bit helter skelter.

I'd say trace the wiring and make a diagram. It will help you understand the advice you will get and the many options you have to rewire your tractor. For instance, I decided to go with a 3-wire alternator circuit when rewiring mine.

I have a 48 or 49 8N front mount changing over to electronic ignition it is 12 volt now with 12 volt coil. MY question is with 12 volt battery and 12 volt coil do you still need the resistor it has points in it now. just wanting to know if resistor needed with points.

If you are using a 12 volt square front mounted coil then you still need to wire the original ballast resister in the coil circuit.

Yes it is still the sqaure coil now when i buy the kit to convert to ei and go to round coil do i still need it.i will be getting kit from here at yt.

You need to ask the folks selling you the EI kit. Not all EI kits are the same.

Thanks bruce i am going to run points for now i had a guy a local new holland dealer tell me i didnt need the resistor with 12 volt bat and 12 volt sqaure coil glad i asked before eliminating the resistor. He didnt seem to have a clue about the older tractors he just try pushin a new new holland on me which i dont need as i use N to maintain 5 acres and do some brush hogging here and there for others.

stalvin........WHY would you want to reduce 12-volts when you use a 12-volt coil. Sure cause fer weak sparkies. Iff'n you have the 4-nipple frontmount dizzy with modern 12V squarecan coil, you still need the "infamous ballast resistor" underneath yer amp-meter. NO ARGUE!!!

Agreed, many "bubba" conversions are SLOPPY wired. .......Dell, a 12V advocate for the right reason that knows 8-ways to convert to 12V and they all work the first time

i still haven't figure why every one wants to convert to 12v,,have a to-20 with org 6-v system, same points/starter/genny from the day i bought it, [used]replaced batt years ago, sits all winter long, starts up no problem summer, [sometimes i refresh batt charge before starting] running at speed to make genny work, no problems yet... not being mean about it, just my $.02

Funny you should ask Bob...

[i:654c4848f0]12V spins your engine faster and starts it better in all conditions, especially if it is very cold or if the engine has marginal compression.
*12V with an alternator is more reliable and uses a solid state VR instead of a decrepit system of points, coils and electromagnets to regulate the charging voltage.
*12V is more forgiving of dirty contacts on/in the entire wiring harness.
*12v is the industry standard and has been for nearly 50 years. That's longer than 6V ever was and getting longer every year.
*12v allows you to run sprayer pumps, flashing lights, winches and a host of other modern accessories on your tractor.
*12V lights are brighter.
*A 12v alternator will easily put out more amps than an old fashioned generator and vr.
*An alternator will charge at an idle. Generator usually will not.
*A 12v system is safer, ie: Most people know how to jump a 12v negative ground car, truck or tractor. How many people know how to safely jump a 6v positive ground tractor with a 12v battery without something exploding in their faces?
*6v requires big hairy - big as your thumb wires and cables throughout the system.
*12v batteries are to be found just about anywhere, are much cheaper than 6v and are usually maintenance free.
*12v lets you use electronic ignition easily.
* And last but not least, what kind of battery is in your boat, your RV, your classic car or even your 4 wheeler or snowmobile if you have them? Why have that odd ball 6V battery?[/i:654c4848f0]

When you covert to a round oil filled coil make sure to get one marked "no external resister needed", then you will not need a resister. On my 1949 8N front mount that I converted to 12 volts and EI I used a "Flame Thrower" coil. With the EI and that coil you can set your plug gap a little wider, I set them at .030. This is supposed to give you more power but I did not notice any difference.

oh i not debating any of your statements,,i just saying that for me , for what i use and do with mine,,my 6v suits me,,funny thing is that it also have 12v cables on it, yet starts OK..not saying some day i may have to change over...
