I purchased a 12 v conversion kit from A.T. and am not sure If I need a voltage reg. on it. My Voltage Reg. is mounted on the 6 v. generator and If I need a Voltage regulator I will attach it w/ ground to a spot within the new wire reach. Any information is welcome. Earl

Sounds like an awful lot of trouble when the easiest thing would be make it work on 6v like it is supposed to.

Sam,
It is easy to make the 6V work the way it did when new. However everything cost more for 6V. I can buy a 12V alt. with built in regulator for under $30.00 and a 12v lawn tractor battery for under $20.00. You add up the cost of 6V gen. regulator and battery and you are talking probably 3 times that. If you need new battery cables they are much higher for 6V. It is also easy to convert to 12V and in the future when you need parts they are easier to find and much cheaper. Only place I see an advantage to 6V is if you are restoring your tractor and want it to look factory new. Then most people I've seen will put a new wet look paint job and say they are factory correct because they are 6V. all the while they have a paint shine you could use as a mirror to shave with.

Have you every tried a 12v battery on your M? Well I haven't but I have used them for years on lots of different tractors and older cars and they work well. Lots of these late model garden tractors have more compression than your M. That M cranks over easy and if you have tried one that didn't work, then you had a bad battery, starter, timing advanced too far or something, maybe all of the above.

I just put a 12V regulator on, and reversed the ground. Worked for about 10 years now. Follow the instructions that come with the regulator. The generator doesn't know if it is a 6v or 12v.

We install 12V one wire alternators on all our tractors and equipment.we buy them at NAPA for about $75.00. With minor bracket modification and hook up 1 wire through ammeter guage and back to starter solenoid,your ready to go.

Don't know if this will help, but I have an old forklift that was a wiring nightmare. I installed one of those one-wire alternators that are sold for hotrods and it eliminated a lot of wire and solved my charger. regulator/problem.

First thing to do is to read carefully- twice- the information that came with the kit you bought.

You can just install a 12V regulator on the esisiting 6V generator. Install a 12 batttery & lights.Change the 6V 1.5 ohm coil for a 12V 3.0 ohm coil. Set to 13.8 to 14.2V volts measured at the battery.

B and D,
That is interesting. I have used a 12V alternator to charge 24V. However I knew a 12V alternator put out 110V+ because I've saw folks hook them up to run small 110V things. Sooo I figgered it wound make 24V with the 24V regulator, and it did. Now my question is, will a 60's ford regulator from a gen. system (I have one)make a 6V Farmall Cub gen. put out 12V?

The Farmall is an "A" circuit charging system, and, likely, the Ford regulator you have is for a "B" circuit charging system

What make or brand is the alternator? The Delcos have all been internally regulated for several years. No need for an external regulator.

Earl, For sure you need some sort of Voltage Regulator, if the conversion kit uses an Alternator?? (and many of those require Negative ground) most are internal and no external unit is required HOWEVER if its just a 12 volt Generator, most mount the 12 volt VR right on the genny as you mentioned.
