    R/R Replacement

    Before I bought my 1100, I was more avid on the GS and Triples forum, and it got me to thinking. The GS had a rock engine, but poor electrical system. Ended-up being great tech tips replacing the shunt-based r/r with a newer mosfet (Shindengen FH022AA) based r/r found on many modern bikes today (I did this repair after my r/r died). I know one of the original guys trying to make a buck used Honda r/r's and sold those, but the mosfet-based r/r's proved superior, and many great how-to's were wrote-up concerning their installation.

    My question is: is this possible to do with the XS with ease? I thought the XS system was wired differently, that may not have allowed the newer r/r's to be wired as easily as the GS.

    But, if anybody is curious as to the pin-out of the mosfet r/r:

    1, 2, 3 wires are stator wires
    4 is positive
    5 is sense (disregard)
    6 is ground

    That's basically what ours are. 3 white wires are the stator with a yellow wire that's disregarded, then we have another plug with two wires from the alternator. You do know Geezer builds an aftermarket R/R unit for our bikes, right? You get to full charge at a much lower rpm than stock.

      There are just two basic regulator types, A & B. One feeds juice to the field coil and regulates by controlling the grounding (like the XS). The other regulates the juice to the field coil. I forget which is designated A and B, but that's the simple version..

        I bought one. It's a very nice component. OEM tend to burn out the rectifier side of things as it shares the same heat sink as the regulator. Geezer's sleek black version has two heat sinks, one for each side of things. Full charging was around 2,500rpm on mine, I seem to recall.

        The Geezer one is such a nice looking bit of kit that it seemed a shame to cover it up!

          Yup, I'm aware. Kinda why I was hesitant to post this thread, as he builds a fine unit, and did not want to cut into his business. I did read that I'm not the first person to bring this up, as I just read a .org member mention the mosfet units. Does not seem to be an issue with our bikes, as I still have the stock unit on mine, as probably many other members as well. It's still a good mod, and I was wondering why the "geezer" r/r did not have a thread in the electrical mod section, let alone any other r/r mod.

            It woildnt be in the mod section since it is a comercial product that he sells through his business.

              So, I'm re-visiting this idea, as I prepare my shopping list over the Winter. Okay, the Mosfet-based R/R has six pins, three of them would be for the stator "white" leads, while one is a sense pin (disregard), and the other two would be positive voltage from the battery and one for ground.

              So, what do you do with the other connector which has the two leads from the alternator? Brown and dark green?

                A regulator designed for a shunt-type charging system won't work properly on a XS. That type charging system uses permanent magnets for a rotor and operates at 100% capacity all the time, with the regulator 'shunting' the excess to ground; it's not really 'regulated'. A mosfet regulator is simply a more efficient version.

                You can use this type with a XS charging system, but running the 'rotor' coil ('field coil' in Yamaha-speak) at 100% all the time won't be good for it. Those 'other' two wires connect to the 'rotor' (brown is 12V power to the rotor as well as being the 'reference' voltage for the regulator, and the green is the 'control' wire) and the regulator controls output by varying resistance to ground through the green wire (voltage/current on the coil, changing it's magnetic strength). The XS alternator is a atypical design different from most bikes, closer to the design of an automotive type.

                The 'geezer' unit that Tony sells is designed specifically for the XS and has a different control voltage 'curve' to increase charging at lower speeds but maintains the same type of control.

                  Back when i had xs750's, i had regulator troubles on one of them. After considerable searching I found a Bosch automotive regulator that worked well, with good low speed output. They had a separate rectifier, but basically the charging system is the same on the 1100 so there's no reason why the same reg wouldnt work. I still have it somewhere out in the garage, and i remember that it was as cheap as chips so I'll dig it out and give the model number for anyone interested. Would still have to find a separate 3 phase rectifier but that should be pretty easy to track down at an auto wrecker.

                    Ahh, well crap. I was hoping it was an easy replacement like the GS was. Oh well, I guess I'll hold-out till my R/R craps out.
