    Kohler/ John Deere regulator/rectifier (wiring questions.)

    I was doing some searching around the internet for a regulator rectifier upgrade for my 1983 Suzuki gr 650.

    I came across this thread for a Kohler/ John Deere regulator rectifier it was very cheap and well manufactured. The thread is interesting.

    I upgraded my rectifier on my bike using the radioshack rectifier upgrade, which i've used on both my bikes, and was very happy with it. however, I am only running a 4ah battery on one of my bikes and didn't want to trust the stock regulator to keep my battery from being cooked, so i started...


    I figure if the suzuki twins are upgrading to the Honda regulators why not use what the Hondas are upgrading to.

    Any chance this would work or is this for a smaller electrical system?

    I have a 5 wire reg/rec and gs500 stator but my new battery won't hold a charge. This has three wires and grounds through the frame. Im not sure how I would wire it.

    Edit: part #: 25-755-03
    I searched and didn't find anything about this.

    This is a separate rectifier/ regulator solution.

    read GS Stator in my signature, and if you can't find a cheap enough SH-775 then find one of the 6 wire Honda as described by Duanage. Might be able to get that for $40 or cheaper.

        As best I know. The 6 wire with sense is best if you are trying to only spend $20 else find a sh-775.

          Sh775 it is, thanks. Is there a wiring tutorial I'm not finding?

            There are several links in my signature related to electrical.

              Aside from anything else, that Kohler reg is a two-phase one.

                He could always put a Kohler motor and mower deck on it, then it would work.

                  Hey, someone might have one laying around and that might be the best option .....

                        Not at all.

                        Some of them are variable-field regulators, they are used on the models with alternators, rather than stators.
