Vanguard stator

[nitro1]

Tearing down my 18hp big block and came across the stator and it’s only a 1wire setup and only half rounded stator and has a option to use a full rounded stator since it has 4 screw holes, so would it work if I bought a full rounded stator and purchase a rectifier to mount on side of my engine for charging ? Or just stick with the one Red wire ? Just don’t know how to charge a battery with the one red wire. Sorry for so many questions first build so many questions :)

When you get your service manual it will show you all that. Your engine should have a rectifier that converts the AC volts to DC. The stator will produce AC volts.

Can you post a pic?

Something like this?

The flywheels are not interchangeable, and it is the magnets on the "flywheel" that determines the output of the alternator. The stator in not interchangeable.
I do think there are a few members, that have switched to a regulated 16 amp setup. I not sure the regulated 20 amp set up will work with 18hp Vanny....
But i am pretty sure you have to buy the flywheel and stator as one unit to make it work....
I thought the 18hp Vannys had the16 amp regulated I guess I'm wrong??

Yes like that, The one I have now is half rounded and didn’t have a rectifier unless they removed it. I’ll post some pics here in a few

[nitro1]

The flywheel is magnetized all the way around if that’s normal or not

The rectifier/voltage regulator is mounted above the starter, has yellow and red wires and plastic plug/clips.

I'm thinking someone monkeyed with that engine. Unless that stator is a single phase? I've never seen one with only one side. All the one's I've worked on had both.

Well I don’t think it was ever touched inside the motor, they might have took the rectifier off but I’m just curious about the half of the stator unless like u said it’s single phase

I'd have to consult my manual.

Came across this page this morning and though it could be helpful or for reference

So looks like my stator is This one here

Yep that's a DC only alternator, no rectifier with that. Those types of engines are usually used in a piece of equipment that doesn't need to power anything except the battery for electric start, say generator or pressure washer. Usually lawn and garden tractors/mowers will have the AC alternator with more power that goes into a rectifier/regulator.

Did you get that from your manual?
