Voltage regulator
 

I am thinking of trying to install a modern style voltage regulator on my 122 you know like the little rectangle ones usually mounted on the side of the shroud on newer engines. has anyone done this? know if it will work?

A solid state rectifier/regulator will not work on a generator. You have to use a mechanical regulator. They last 40 years anyway, so it's not like they are a problem.


Aren't you a mechanic?.......:bigthink:
You should know that.

They do make such a thing (I.e clover DR110), though I haven’t personally used one. It’s a lot more complicated than just rectifying ac voltage, but it’s not an unsolvable electronics problem.

One of the solid state rectifier/regulator functions is to convert ac current to dc current. You will need to rewire part of the tractor to get it to work right. You will need a different flywheel-charging system to make it work. Easier to find another regulator.

Pretty cool Gompers! $165...not so cool.:bigeyes:

Interesting and maintains the same external look. $165 though ouch.

Mechanical regulators/starter generators work quite a bit differently than a regular rectifier situation you’ll find on modern engines. You get dc voltage directly from the starter generator, and the regulator regulates how much voltage and current by controlling the grounding of the field coil. It also stops battery voltage from feeding back into the starter/generator.

It’s a whole different process than rectifying ac from a stator/alternator type situation.

You could probably build one for a lot less, but you’ll need to spend some time doing the same engineering those folks have done. Build a current sensing circuit and a voltage sensing circuit and an op amp and a power mosfet and you’ll have something vaguely functional.

But it’s not as simple as just plugging in a solid state rectifier.

Gompers.... Believe me, Merk is well aware how the systems work. :biggrin2:

That wasn't what he was suggesting..... he said:


He was referring to R/R as found on any Mag motor, or late K series... or CH or _______.


Which is what I said in post #2. Plus, you don't need to rectify voltage that is already DC. You just need to regulate it. So, it's a mute point... of coarse a rectifier won't work. It's already DC. So the answer is NO. You cannot install a R/R in place of the voltage regulator.

As far as the point of a solid state v-reg.... who would spend nearly triple the cost of a standard v-reg anyway? They're $60 and last 40 years unless you fry them, or buy a cheap one.
