    Best to go series r/r route, like a SH-775 costs about $80. Member duaneage sells decent Shindengen shunt units with wire connectors. If you go ebaying, look for compatible Shindengen units -avoid most others,as lots are poor quality.

      Search the forum for "Polaris R/R", read up, and buy one.

        is it a stock type R/R having 3 stator wires, a ground wire and a power out wire?

        .... or is it a "Honda" type also having another wire ("sense" wire)? If it is, and the sense wire is disconnected (or other wize detects low voltage) the R/R will put out max and battery voltage be way high like 18 (or more) volts.

                Likely a aftermarket unit since it has 3 yellow wires. You need a new r/r. Might as well read up on charging issues at same time. It ain't a quick read, but don't just throw parts at bike and call it done!

                  bought a new sh775 r/r from Polaris no harness. Have three stator wire(one Yellow, one white with blue stripe, and one white with red stripe )does it make a difference what pin they go on? I understand the red & black wire but not the three stator wires.

                    The order does not matter just make sure they go direct to the r/r. It will leave you with spare wires in the harness.tspe them back they have no power on them.

                      The three stator wires make no difference what order they are connected in.....as long as none of them are connected to the red or black locations.



                      I bought a harness from Triumph, p/n T2500676 from Bike Bandit (same online dealer that I bought the Polaris Razr 800 R/R from)

                      Soldered and heat shrunk the wires to the stator wires.
