    Bad R/R affect upon new stator?

    I've just installed a new stator on my 1100G. The PO replaced the R/R but didn't ground it properly. Probably the reason the stator went out. I suspect the R/R is bad because the rubber insulation around the ground lead where all the wires exit the R/R shows signs of having overheated. My question is; now that I have properly grounded the r/r, can I damage the new stator if the r/r is indeed bad? FWIW, I was getting a little less than 12V at idle and a max of 13 @5k. The results of the "Stator Paper" tests showed that one leg of the stator wasn't putting out enough voltage. The other 2 legs were slightly over 50V if I remember correctly. So, in a sense, the r/r was working but that melted insulation bothers me.
    Your opinions and responses are definitely, as always, appreciated.
    Thanks in advance,
    Willie

    Install the parts and check the output. If the R/R is controlling the stator output like it should I'd leave it in place and worry about something else.

    BTW, did you route the stator wires direct into the R/R, thus cutting out the stupid factory out and back loop to the hand control?

      I haven't yet, but had every intention of doing that. I've already highlighted those wires on my wiring diagram to make it all the easier.
      Thanks for responding.

        When you get the RR I sent refer to my wiring diagram at the bottom of my posts.

          I appreciate the advice and am leaning towards hooking up the old r/r, since its already in place, to the new stator and seeing if it works. I have a "duaneage r/r" on the way but bought it with the idea of having it for a spare. Bottom line remains as originally posted......can a bad r/r damage a new stator?
          Thanks again,

            Yes. A bad R/R can and will damage and eventually overload and fry a new stator. With that said, it's not going to hurt it to run the bike for the small amount of time it takes to do the testing.
