12 V. conversion for a Cub

I need aschematic to convert my 59 Cub from 6 v. to 12v. also wonder which 12 V. ALTERNATOR WOULD WORK BEST.
Thanks for any and all help extended to me on this.

Have a look on Charliesrepair.com, he is Charlieu on here. Very well layed out wiring diagrams that anybody can follow. He also makes kits to put alt on to old Ih tractors.

Why would you convert it to 12??? It has a 60 cubic inch engine and they turn over and start just perfect with 6! Fix the battery cables and grounds and do it right!

Because dealing with generators and voltage regulators is a PITA!

I don't have it book marked but if you search for "Bob M wiring diagram" it should show. Or perhaps someone will post it for you.
A hitachi 14231 alternator out of an early 80's nissan pickup is the most recomended. I got mine from rockauto for about $30.
Sure is alot handier than having to worry about polorizing the generator everytime the battery goes dead, has to be disconnected, etc, etc.

I bought a kit from Charlie for my 48 Cub. Switched to 12v because I wanted to use my 12v sprayer with it. Great guy to work with and kit worked great.

I would fix the 6v system rather than buying new battery bulbs and the trouble mounting an Alt. That small Cub engine will always start easy if you have it in shape.

Well said.
They go round and round on this subject on the Ford N board too so I made up a list of reasons to go 12V.
[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 an old fashioned system of points, coils and electromagnets to regulate the charging voltage.
Solid state is better, more accurate, more dependable.
*12V is more forgiving of dirty contacts on/in the entire wiring harness.
*12v is the industry standard and has been for 50 years.
*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 generally will not.
*A 12v system is safer. For example, Most people know how to jump a 12v negative ground car, truck or tractor. Not many people know how to safely jump a 6v positive ground tractor with a 12V battery without something exploding in their faces or getting themselves run over.
*6v requires bigger, harder to find wires and cables throughout the system.
*12v batteries are to be found just about anywhere, are cheaper than 6v and are usually maintenance free.
* And last but not least, is this your only 6V machine?
What kind of battery is in your boat, motorcycle, lawn tractor, RV, your classic car or even your 4 wheeler or snowmobile if you have them? Why have an odd ball battery that can't jump or be jumped by anything else? [/i:654c4848f0]
