    A note to old forum members...
    I receive numerous requests from people who can no longer log in because their accounts were deleted. As mentioned in the forum FAQ, user accounts are deleted if you haven't logged in for the past 6 months. If you can't log in, then create a new forum account. If you don't get an error message, then check your email account for an activation message. If you get a message stating that the email address is already in use, then your account still exists so follow the instructions in the forum FAQ for resetting your password.

    Have you forgotten your password or have a new email address? Then read the forum FAQ for details on how to reset it.

    Any email requests for "can't log in anymore" problems or "lost my password" problems will be deleted. Read the forum FAQ and follow the instructions there - that's what we have one for...

  • Returning Visitors

    If you are a returning visitor who never received your confirmation email, then odds are your email provider is blockinig emails from our server. The only thing that can be done to get around this is you will have to try creating another forum account using an email address from another domain.

    If you are a returning visitor to the forum and can't log in using your old forum name and password but used to be able to then chances are your account is deleted. Purges of the databases are done regularly. You will have to create a new forum account and you should be all set.

Looking for a SH775

i bought a SH775 a while back from the same seller, was cheap and fast delivery. Now i see they will not ship to UK.
 
I looked through our local Kijiji ads for "ATV and Snowmobiles - parts". I found a guy who was parting out a 2013 Polaris 800 snowmobile. I called him and asked if he still had the voltage regulator and if so could he send me a picture of and numbers on it.

So I went and got it after handing him $80 Cdn.

This one looks like the real deal.
 
Nope, not an SH775.

Four things jump out at me.
1. There are no round nubs on any of the fins.
2. The bottom plate is black, not silver metal
3. There is no "SH775" on the back fin
4. It's too clean, as well as black.

All of the SH775 regulators:
- have 8 round nubs on the fins.
- The bottom plate is silver metal
- they have SH775, plus a couple more letters on the back fin
- used items in this price range are usually dirty and are a dark gray
- don't come from China

Here is a link to a good one, notice all the points that I mentioned are shown in the pictures.

So finally got my stator and SH775 installed and hooked up. The voltage across the battery is about 14.3V no matter the RPM.

Here is something you might find interesting: my stator was burned out so I bought a relacement on eBay. While I was waiting for it to arrive there was no stator inside the magnetic rotor. I think this might have caused the magnetism to weaken because when I finally put the new stator in I started the engine and measured the AC voltage between the stator leads. At idle I only got about 13V. Then a couple of weeks later I repeated that test and got 15.4V between stator leads. I'm thinking that having the new stator in place brought the magnetism back.

So maybe, as a rule, you shouldn't leave the rotor empty for an extended period. Leave the cover with the old stator in until the new one can go in.

I should add that the SH775 mounted in the same location as the OE regulator, under the battery box. Screw locations evened lined up but had to use shorter screws.
