    Battery "boiling" over

    I just bought a GS700ES. I guess it is overcharging , it dumps acid all over.Is this strictly a rectifier/regulator fault , or can anything else cause these symptoms?..........thanks
    Can any other rectifier/regulator be used ? These Suzuki ones seem hard to find

    My '79 1000 was loosing a lot of water,not really boiling over, but evaporating too soon. I had to re-fill every 2-3 months. I also had several wiring connectors getting hot. I read the ''Stator Papers'' at this site and bought the Electrex Regulator/Rectifier ($110)and have had no more problems since.(3 1/2 years) On my model, the 3rd phase coming from the alternator was not regulated and it caused the stator,etc,to overheat. The Electrex R/R fixes that. I don't know about your wiring system but that would be my guess.
    And on the seventh day,after resting from all that he had done,God went for a ride on his GS!
    Upon seeing that it was good, he went out again on his ZX14! But just a little bit faster!

      The problem of overcharging and the subsequent cooking of battery, stator and regulator/rectifier on all old suzukis is due to bad design. Everyone seems to recommend changing the R/R for an electrex unit, and this is one solution, but what also works is to run a single heavy guage wire from the regulator body to the battery (-) terminal. With the original set up, the regulator is eventually earthed through the battery box, frame, engine and so on. Any resistance in this "train"of earths will cause overcharging problems. Put a multimeter across your battery terminals with the engine running at 2000 or so RPM and record the voltage. Connect this single wire as I suggested and measure the voltage....any difference?

        Hello Guy. If you already have the Electrex R/R, would it be worth installing the extra ground, or not really necessary? Thanks! KK.

          Battery boiling over

          I ran the bike with a meter across the battery. It was reading around 15v DC , didn't go any higher. I imagined 15v to be "acceptable" ?? After a few minutes tho , I could near the battery bubbling away like it had been on a charger for several hours. Any ideas ?

            15 volts is to high, it should not go over 14.5 volts, run a ground wire from one of the regulator mounting screws to the battery ground post, Guy is correct, the stock grounding system for the regulator/rectifier is poor at best, bad regulator grounding is one of the major charging problem causes.
            Keith, a ground to the battery will help a electrex regulator also.
