    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.

I have a 1983 gs550e ,and 2 weeks ago I went out for a ride and when I was comi9ng back,I stopped at starbucks to get some water,when i got bvack on and tried to star the bike back up,nothing,I got the bike home and found that the battery was completely dead and had noacid in it,I put in a new battery and tested it and it was putting out from 13.25 volts at idle to 18.77 volts at 2500 rpm,so I did all of the testing that io read about on here and found that it was the rectifier,i bought a new one and put it on today,I started the bike and tested it with the tester and it was putting out 13.5 at idle to 14.27 at 2500 rpm,I notice that there was some smoke coming fro mthe plug that plugs into it and shut it off,i touched the rerctifier and it was hot enough to make me pull away quickly,I took the tank off and traced all of the wires and found none that were grounding out to cause it to get hot,I am wanting to know if anyone else has encountered this problem,or if they might know what else may be causing this problem,sorry for such a long post,:cool:
 
Sounds like a bad ground. Did you run the R/R ground direct to the battery?
 
OK I'll bite.

What type of Regulator did you replace the old with?

Does the R/R get real hot even at idle?

The voltages seem normal, but just to leave no stone unturned, make sure you wave love voltage drops across the R/R (+) to battery (+) and R/R (-) and Battery (-) at 4000 RPM.


I have had an R/R get hot a idle and it was poor connections on teh R/R (+) lead but I also had low voltages not 14.5 volts.

gets hot at idle,i replaced it with the factory one,
 
if there is no voltage differential between the R/R and the battery it is not dropping any voltage and therefore will not get hot. Check the voltages as mentioned.

sorry mang,my mind is on extreme overload right now,i didn't even read that part,i appreciate the help,gonna do that tomorrow.:cool:
