Any visual difference between cut out and electronic regulator?
 

How can you tell the difference between 1) a simple mechanical cutout 2) an electronic regulator and 3) a cutout that's got a diode in it . Is there any simple way of checking what's inside them without taking the top off or watching the ammeter to see how they perform?

With a meter on regular cutout "B" terminal should be open to the case, and other terminal
The "A"should have resistance to the case, open to B

A diode cutout should be open to the case from either terminal, and should test like a diode between A,B, --- the direction of flow depends on pos--- neg ground

Never tested or took apart a fun project regulator, but I suspect some reading in all directions

No can't see it

My units from Fun Projects have a sticker on the bottom side. Take the "cutout" off the generator and see if it is marked or stickered on the bottom.

Thank you all.

If it is a Fun Projects voltage regulator, John Regan the manufacturer said this in 2011 on the MTFCA forum.:

“All of our voltage regulators are easily discernible as to 6,8, or 12V as follows:

On the underside of the base the 8V units are stamped with a letter "A" while 12V units are stamped with a letter "B". No stamp at all and it is then a 6V unit. Positive ground Voltage Regulators have a steel washer in place of one of the center insulating washers. As pointed out - a rivet in one of the center locations designates that it is a cutout. Hope this helps.”

Look for a steel washer and no rivets in the center.

When I recently replaced my original cut out with a new diode one I used the old cover on the new cut out and painted the legs of it black. You can't tell the difference that it's been changed.

If there is no letter (I have a 6V positive ground diode type with no letter) on the bottom what I have picked up; (funprojects) there is a laser cut "V" on the bottom, if it is bent up it is a regulator, if left flat with bottom it is a diode type. If it out of warranty, take the cover off and look. They didn't make a lot of "CUTOUT" types as they were meant for cars that got driven much (more show then go).
