Alternator conversion? or keep the 6 Volt

Postby Brendan In NC » Sat Oct 26, 2013 9:32 pm

Well iv gotta ask. the main thing on the 64 is that all of the original wiring regulator generator is all still together hooked up not working but still there. what im asking is, is it better to keep it 6 volt an have everything redone or switch it over? right now i have it jerry rigged with a 12 volt battery an coil should i go have the generator rebuild an tested an hook everything back up an get it working if possible or switch it. :? i would replace the voltage regulator after rebuilding everything i was wonder if anyone knows of a good quality one even imported. iv already bought a new belt an have a battery may get a coil or see if my old one is good :roll: anyway someone give me you input on this i just wanna see what anyone else thing we should do, now this Cub is not gonna be used everyday unless i ride it around :wink: but as long we can get it charging an firing right ill be glad!

6 volt works great and is usually a cheap fix

yea but the main thing is finding a cheap but GOOD regulator!
iv had these book marked for a few days im just trying to find a working regulator that will charge the battery so i wont have to leave it disconnected all the time. i just wish i knew which was good an which was not at all.

first determin why the 6volt system isnt working It is usually as simple as taking the top off the regulator then cleaning the contact points. ( battery disconnecte ) There are no cheap good regulators. Most cheap regulators are made in china and aint worth the time installing. A good regulator made in the USA will cost around 70 bucks. when I am faced with replacing a regulator I usualy convert to 12 volt using a delco 10SI one wire alternator.. It is simple and cost around 45 to 50 bucks.. Last week I was at a tractor show with my 1957 international S 160 truck.It is 12 volt from the factory. When I got home the generator was on fire! That is the second generator and 3 regulators in 6 years. I replaced the generator with a one wire altinator.. Made a bracket to mount it.. rest was a piece of cake..

If it needs a regulator, $70, and a genny rebuild (last one here, $125), and a battery, My Polish math skills, say 12 volt conversion. Also, 12 v batteries, are much cheaper than 6v, most places. (Most of mine, don't charge. I charge batteries, between uses. Too cheap, to repair, or convert)

I have a 35 amp 6 volt generator and the original voltage regulator from a 1950 Chevrolet. The regulator housing looks like crap, the inside looks like new. The base bracket required is longer than than the original Cub but there is plenty of space for it on the Cub. I have considered getting one of the electronic conversion regulators and putting this on a Cub-- only the sharpest of eyes would notice the change. That would be as good as 6 volt generator setups ever get.
This setup in 1950 was as sophisticated as the 6 volt systems ever were. I suspect that the regulator I have is the original. A relative bought the vehicle new and I saw it that day. These parts were salvaged when the thing was parked years later after the engine block cracked.

The only other question you need to ask yourself is, do i want to stay original or have a working tractor.

Where can I get an electronic 6V positive ground regulator? That could solve a lot of problems. I have found references related to antique cars but no specific information.

I have tired the expensive American made regulator and I am not convinced it is doing as good as the original regulators. The American made regulator does appear to be much better quality than the imported regulator that I have. I have asked before in another thread if a good schematic of the 6V positive ground regulator used on IH tractors is available. I found a diagram that shows the circuit but not any of the resistance values. I have enough old regulators that I can probably fill in the values by measuring. I would like to see if I can repair any of my original regulators, since they seem to be better units than anything I can find.

If the goal is to save money, take the generator off and don't have a charging system. Particularly if you don't use the tractor regularly, you need a $17 battery maintainer anyway. Even with battery ignition, it will run for days off the battery. With a magneto, it would probably run half the summer.

The only situations where this isn't a viable option is if the tractor is parked somewhere with no electricity to run the maintainer or if you run it extensively at night. For night operation, a couple LED lights my still be the cheapest option.

I have not done business with this company, but all the references are good from those who claim to have done business there. Cost is probably no more than buying a couple of the conventional regulators. They can install the electronics in an old regulator housing for original appearance.
But converting to 12 volts with an alternator will be a lower cost solution.

Just found this about Jeffers. Probably someone is continuing with the business.

Thanks Bus Driver,

I wonder what the circuit looks like for a good electronic regulator. Schematics for this sort of thing don't seem to be public knowledge. I built a lot of electronic gear for Hi-Fi and also tube gear and have learned from those projects that there is not much you cannot build if you have a good schematic.

To take Jim's suggestion one step further....take off the generator and buy a hand crank. A young guy like you can do a lot of crank turning. 8)
