The original subject was "Voltage Regulator on a C".

Did you ever get the four post voltage regulator to work? I bought an identical one but do not know where to put the gen wire. I think I know where to hook up the battery and field from the generator.

Thanks, Wayne

the terminals should be "B" battery, "F" field or ground terminal on the generator, "G" or generator (A terminal on gen), and the last terminal on the regulator is "L" which ment load or light. this terminal is hot (battery voltage) when motor is running. THe L terminal is normally shut off with the key switch or on off switch. Some regulators might work without a wire on the "L". you can also connect it to the B terminal and test if things work. -- dont forget to touch the G and B terminals together for 1 second to polarize the system prior to starting the motor.

Isn't there a tab on the regulator labeled "GEN" or "ARM"???

There are four terminals on the brand new voltage regulator from Yesterday"s Tractor. It has three visible terminals marked L, Batt, and F. Look it up, there is a picture. There is sort of a hidden terminal( number 4) behind the regulator with no marking.

I have been told that the terminal on the back is the "gen" connection terminal by some on this site. I will find out tomorrow when I hook it up.

This voltage regulator is made for a John Deer tractor and is a John Deer part. It can be used on other tractors also apparently. Nobody, not even people at John Deer know who made the voltage regulator for them or how to hook it up on an Allis B. At least the very nice people I spoke to at John Deer.

This voltage regulator has no cut out. So I assume I can use my old cut out in series with the regulator. I have no ignition switch, I have a magneto and no three position switch. Until now, I have the field grouned to allow full charge from the generator using only a cut out.

1.) Do NOT use a cutout in addition to the regulator. There IS a cutout IN the regulator. Whoever told you there wasn't one is "full of beans"!

2.) Since you have identified the L, Batt, and F terminals the remaining one HAS to be the "GEN" or "ARM" terminal (different words for the same thing).

I replaced the cut out with the new voltage regulator yesterday. I used the terminal on the back of the regulator as the generator output connection. The "L" terminal was left alone and I induced a brief current across the "batt" and the "G" terminals on the regulator prior to starting the tractor. It is working fine. I will have to wait for a few days to insure that the regulator naintains a charge on the battery.

The battery was fully charged when I installed the regulator.

Thanks for preventing me from doing something wrong on the hook up.

GREAT job! in reply to Carbonfibers, 03-16-2008 11:48:40

GREAT job!

It's always nice to hear something works like it's SUPPOSED TO!

Especially, nowadays, when so many of these products come from "The Land of Almost Right"!
