    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.

Am going to buy a decent test meter tomorrow to begin working my way through the stator papers, however, I had a quick question. Is the regulator rectifier supposed to get wicked hot when the bike is running? I can't even touch mine and I was wondering if this was the norm or an indication of a problem with the regulator.
 
a hot rr is both the norm AND the problem - as it may lead to a failure
the heat sink is undersized on suzuki units and their location out of fresh airflow is a prob on some models too
but an overly-hot rr may also be a sign that it may be on its way out - so do test it to know for sure
poor electrical connections contribute to heating as well

Thanks for the info. I was wondering why they had it tucked up underneath like that. Seems a bit cheesy. I'll check connections tomorrow and hope that is it. I don't feel like dumping money into a stator or a regulator but I'll gladly take the lesser of the two evils.
 
a popular upgrade is a (used) honda rr
some people built additional heatsink or relocated the unit so it gets more airflow
 
I have a suski 1985 gs 700. Do you know what honda RR I may need?
 
send a pm to "duaneage" on the forum here
he should be able to sort you out

If it were my bike and I was going to substitute a R/R from another bike, I would go with one from a KZ750 four cylinder. They're better designed and fail less than 1 in 4 when compared to the same Suzuki part.

You would connect it as follows.

Kaw - Suz
Yellow - yellow
black - black
red - red
brown - orange

Or you could buy a new aftermarket one...

Try the RR ground wire right to the negative battery post. It should shunt more current and make the RR run cooler.
