    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.

Stumped by charging output problem

If you have big drops clean them, if not then the stator is going out.

What is a big drop?

I have a new Caltric stator and gasket in anticipation that one day the old one will fail, but have not had it installed. That is another "big job" for me, and likely will need to find some help.

0.6v is a big voltage drop !!!

Read GS stator for the nth time. It will explain the r/r issues that are now solved.
 
You have a series r/r right?

Not sure. What is a series R&R?

I am using one from Rick's Motorsport R&R, which some on this or another motorcycle forum say is a good product. The leads are compatible with the original harness on the GS450GA. Cannot find out anything more about the specification.

A little history. The original R&R went bad around 2k, and i replaced it with a used Honda R&R that Steve had on his list. That went bad recently (after a few thousand miles), letting 18v come across. That may be why my battery died and one of the coils was burnt.

Did one more test before it got dark. The negative-lead test shows about 0.4-0.5 volt drop. Of course, I did not go back an recleaned the red lead connection because I am out of cleaning solution. So this may not be a valid test.

Reading the suggested calculations from your PDF, does that mean I am losing about a volt? That would mean that the output would have been 14.3-14.5 volts without the drop through the leads, which would otherwise be in the ideal range. I can be completely wrong.

I will try to find time to read more carefully your GS stator.

I do greatly appreciate all of the help.

To the OP:

I have been following this thread, although I have not posted anything in it yet. I would like to make 3 points:

(1) It is not clear to me exactly how you are cleaning the connections, but I would like to suggest that if you are just spraying the connections "as is" with contact cleaner, this is not good enough. You should pull apart/unscrew the connectors and first brush them with a small brass/stainless steel brush, or use fine wet and dry sandpaper to get them nice and shiny. Only then spray with contact cleaner, before re-connecting the connections. Alternatively use Naval Jelly for cleaning the contacts. You will find many threads on this cleaning process with the "Search" function.

(2) Secondly, for best long-lasting results, the newest information on GSR actually suggests not to use the Rick's products, but rather the SH775 Series R/R, which is a Polaris ATV part. Again, using "Search" will bring up many threads on this subject.

(3) Finally, you will never get optimal performance unless you add additional earth wires as explained by Posplayr in the excellent information links in his signature. You do not have to cut your original wires, just add some new ones. In one of your previous posts you said: ..."I can try your suggestion about rewiring the ground wire (B/W), but I don't want to do that unless necessary. I don't want to cut into the original wire, and I may not do a good job with the rewiring. This would be a last resort".

Upgrading the earthing system is one of the FIRST things you should do to ensure proper charging performance.

I can assure you that I am not an electrical fundi at all, but just by reading Posplayr's information (yes, sometimes 3 or more times over!) and then doing what is suggested, you will have all your Volts back.

Good luck!
