    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.

My question is a pretty simple one, I am restoring a GS650G basket case from the frame up. Powder coating the frame, found a NEW tank, covers and tail piece and will get a new stock seat cover so she should look pretty good when it is done. My concern is that I have a couple of 81 GS550T's that I have fully restored and my buddy and I take a tour on them annually reliving our youth with the same model of bikes we had new. Last year we experiences issues that were, as far as I could determine, from the charging system heating up so rectifier/stator issues I'd suspect. The one bike kept blowing fuses after a long run at higher revs in the heat. The R/R and stator were stock and my suspicion is they're likely due for replacement. A spring project will be to test them and decide what to do there depending upon what I find.

With this new build (GS650G) I am inclined to simply buy a new stator and rectifier so they're good to go from day one. My problem is I can't seem to find a definite answer on which rectifier is the best. Seems that Rick's stators are worth the money but I am not sure whether a Rick's rectifier is the best choice or whether I should get a SH 775. I've read a lot of the posts but I am still unclear.

If there's a good rationale available I'd love to hear it on which to get.:D
 
Concensus is that the SH775 series type is preferred due to the fact that it ?switches off? when the battery is charged as opposed to the shunt style that dumps extra current back to the stator when the battery is full. This causes the stator to run hotter. This a very simplistic explanation, but I?m pretty certain that is the gist.
 
The switch off part was what I wasn't getting and now understand. Next question is where's a good place to buy one and know it is not a "fake"?
 
You want "new" or "used"? :-k

I recently updated my thread from a few years ago, showing prices for new SH775s. Click HERE to see that thread. (All the info you need is in the first post.)

If you don't mind getting a used one, let me know, I will find a few on eBay for you and send you the links. There are getting to be more and more copy-cat R/Rs out there that look like the SH775 and the ads say "replaces Polaris R/R" or "fits Polaris Razr" and other such wording, but they are just updated versions of older shunt-style R/Rs, not a series-type that you are looking for.

New or used? Well I figure I may as well go new if I putting a lot of effort into this rebuild and I want it to be dependable ... Pro Caliber seems to still have it for $134 shipped - does that seem correct by your account? Here's the numbers/description they've listed: REGULATOR-3PH,35A,SERIES,105C 4012941 REGULATOR-3PH,35A,SERIES,105C . https://shop.procaliber.com/oempartfinder.htm?aribrand=POL#/s/POL//4012941/1/

And that's great info on the clone/rip offs that are out there. Seems some will go to great lengths to deceive people these days.

Thanks to you and Dorkburger, you've been a great help with this!

I did not check the price today, but they were the cheapest as of the date that I updated that thread (11 FEB 2018).

If you would be interested in a used one, click HERE to see one of the two that I just saw on eBay for $45. You can clearly see the "SH775" imprint on the back fin, which pretty much assures you that you are getting the real item.

As far as the reliability of a used item, I have bought several (for my bikes and a few others), have never had a problem.

Your money, your choice. :-\\\

For $45 it is worth a try - I bid on it and will see how it tests out/runs. Thanks Steve - the amount of work you do for others here is pretty amazing and appreciated.
