    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.

Over charging question

I am running a 1982 GS1000sz with the charging system intact. This a race bike, so no lights, blinkers, etc. The output is hovering around 16v at the battery. I pulled 1 of the 3 legs and am getting around 15.7v I pulled 2 and the system doesn't charge. Replaced the rectifier with same results. What is a quick fix my situation? Thanks for any input. Joe
 
If the replacement R/R was good, I think I would look at the grounds first. Using a stainless steel star washer on both sides of the ground terminal helps insure a good connection. I replaced the motor to the battery ground with heavier wire, and have the ground from my compufire unit directly to the battery in addition to the case of the unit being grounded directly to the frame and the stock ground points. You are in battery frying territory with those voltages.

I forgot to say that the stock system was designed assuming a load for the headlamp and tail light. Two stator leads should charge it properly. Three will overcharge it. Before the Headlight always on laws Suzuki switched off one stator leg with the headlight.

Good call. Mr. Posplayer is probably also on to something.

If you are using an old style R/R that only has one SCR on one leg, they can overcharge because they can only limit the single phase as you were doing when you removed a single phase. Because the are no lights and other loads, that may not be enough but pulling the second phase is too much.

Get a later model R/R that has SCR's on all three stator legs and see if it can regulate down. The 83 ED's have 3 SCR's, the 81 GS750 was a single as I recall.
