    Are the Reg/Rect year/model specific?

    I think my regulator/rectifier isbad on my 79' GS1000. It doesnt appear to have any resistance between any of the leads. I was checking around on ebay, and didnt see one specifically for a GS1000, but did see one or 2 for the 850's. Do I need a specific GS1000 reg/rect, or can I use one off another bike?

    you will probally need to rework the wireing, but any 5 wire reg/rect will work. If you're smart, you'll NOT buy a suzuki part. I use a honda part on my bike. one from a CX500. Or an electrex part.

      so you used one from a cx500? By rework the wiring, what do you mean? Making all new grounds and whatnot? Enlighten me please...


      For that matter, could I use one off a new bike?

        You can use one off a new bike. The technology hasn't changed. Just on the newer bikes they frequently use connectors that are custom and part of the r/r and not on leads coming from the r/r which makes it a lot more difficult.

        The only funny thing i had to do with the honda r/r was hooking up a line to switched +12v. There are three leads to the stator, just like on a suzuki. And there's a negative and a positvie lead.

        Look up "my regulator rectifier mod" I think... it's in tips and tricks.

          Cool, I'll check that out in the tips and tricks...


          I wonder if this would work...

            While on ebay, I just came across 2 or 3 from the cx500. I am going to call around tomorrow and see if I can find one...If not, I will try to snatch one off there...




            Just to be sure that this is my problem. If I didnt have any ohms between any of the wires, it has to be bad, right? The 3 wires from the alternator were putting out over 80 volts at 5000 RPMs, so I am guess that it is fine...

              When you say "doesnt have any resistance on any" do you mean it read about 0 ohms (short) or did you mean no continiuty (infinite ohms). I suppose it doesnt matter because they should not all be the same anyway, some low ohms and others higher ohms, and different when change polarity with meter.

                I had readings of 0 ohms....

                  A rectifier is a set of four diodes which pass current one way and not the other. So you need to test current flow in both directions. 0 ohms one way and a few the other is OK.
