Can anyone identify this Regulator

Who makes it? Is it 6 or 12 volt?
I picked it up not knowing anything about it, figuring that I will eventually use it be it 6 or 12 volts.

it is not a regulator. it is a replacement for a cut out relay.

it is simple and consists of a diode. not much else.

i imagine it is for a 6 volt system as i do not think anyone has developed a 3 brush 12 volt system.

Yup, exactly what John said; ain't nuthin' but a big diode. A solid-state, one-way electric "valve". When the generator starts puttin' out it will pass current to the battery but it won't let the battery discharge through the generator when the bike is shut off. A lot of the old british bikes used the same system, it was called a Zenor Diode or something like that.

I wonder if its wired so it will shut off the idiot light on the dash when it starts charging? It could be made to do that by providing equal potential on both sides of the idiot light when genrator output equals battery voltage.

Nice pictures of your knee Dale, did you get some new Levis for your birthday or something? NOBODY has jeans that clean!, hell, real mechanics usually don't have much material left in that area.

just kidding.......

Well,,,, As you guys can plainly see, I am electronically challenged. I only know enough to make me dangerous----very dangerous......
Basic wiring--That's me..
I looked at the unit pretty well. It looks like the two lugs that are on one end are both making contact to the same circuit board, and both run through the diod, and out the end with the single lug.
Good guess on the birthday jeans! Mine used to wear out on the knees, now they wear out on the posterior. :lol:

if you keep your bike 6 volt 3 brush that unit will work quite well.

as for the generator light, that is an easy modification requiring only an insulated dash lamp socket and some minor rewiring under the dash.

however, if you plan on 12 volt you will need a proper regulator. a delco 2 unit, bosch sportster/vw unit or a frankenstien home made one like i have. also the cycle electric end mount works but is way ugly imo.

keep in mind the home made one can work either 6 or 12 volt.

I replaced one while rewiring an old Triumph and did a lot of swearing at Lucas, god of darkness.

I have only tried three of the diode relays as shown, and all three were bad out of the box. Cheap mechanical relays from the same importer worked fine. The 'inline' relays that do not look like a relay work well also.

And to add to JohnHD's comments on regulators:
There are many sources of solid state "box" regulators for 6 and 12v two-brush systems that can be easily mounted on a bracket beneath the generator on the motormount bolts. CE makes the finest of those, as well as their famously ugly endmount generator combinations.

I believe that CE makes the only reduced-voltage box regulator for batteries in a hot oiltank (CE-102L).

In 3000 miles, I have been through two 6v HD batteries. Countless headlights, and a few tail lights. I have tuned the third brush for more voltage, less voltage and no voltage. LOL

Towards the end of last summer, I put 2 smaller 6v vented NAPA batteries in parallel into the battery box--light duty.
These batteries have lasted over 1000 miles and have not lost any acid.
Low beam is out, but high beam is hanging in there.

I plan on trying to find the parts to run an H4 bulb in my stock headlight bucket, so I can carry a couple of extra bulbs, and maybe use a little more wattage than the sealed beam I am currently using.

I have read about converting the 32E to 2 Brush and using a real regulator. I understand that this setup should keep up with the headlight at highway speeds. What about marker lights/parking lights. Eventually I will use LEDs. I am going to try to stick with 6v

i have a halogen 6v set up, if you want it perhaps we can work something out.

How are the halogen bulbs holding up to the vibrations?
How many watts are the elements?
Is this the H4 bulb or the sealed beam that you have?
Will the two brush genny carry a halogen?

i am running a regular sealed beam now, i had the halogen on it for one summer.

the elements are 55/55watt i believe, i'll check saturday.

i cannot comment on weather your 2 brush would run it. you would need to check it with an ammeter. my genny light stayed out while i had it running.

i no longer need it, and it can be yours if you like.

shoot me a private message...

This cutout relay replacement, as others have written, is just a big diode that is set up so it conducts in the forward direction when the voltage from the genny is greater than that of the battery, by whatever the forward drop of the diode is(usually about .7V).

And it doesn;t conduct ata ll if the battery voltage is greater than the genny voltage; so you don;t drain your battery feeding the generator armature coils.

The Zener diodes used on britbikes were actually used as a voltage regulator. They are different from regular diodes in that they WILL conduct when reverse-biased, at pretty low voltages. That voltage is the voltage rating of the Zener diode, and they come in just about any voltage you want. The way they are used, is they are connected in parallel with the battery(if there is one) or from the generator output to the ground, wired up so that the "line" on the diode is attached to the "plus", so that it will not conduct until the voltage across it goes above it's rating-then it will conduct, enough to drop the voltage down to it's rating. Zeners essentially waste whatever extra voltage there is as heat, and some of them are covered with fins, etc, to dissipate this heat.

I had one of them 6 volt electronic relays also One Time , and it quit working...on popping the case open..i looked closely and seen that the makers of that unit...had "Scratched Off" the numbers on the diode so you would have to buy another one.
