Just make sure you keep an eye on the max voltage that is found across the battery terminals at 4k and 6k rpm. Check using multimeter from time to time to see if the RR is healthy. Any sign of overvoltage and replace the RR asap. Faulty RR tends to eat up all the electrical/electronic devices and also result in a fire [which happened in my case]
Also just take a look at KBPC3510. It will make your job easier.

Dear Friends...
I have done rewinding (in a seperate Stator) for my UG III with 19G wire, 75 turns/pole. Connected directly to APE RR with higher guage wire (no groundings) & Output of APE RR to Battery. Also output of rewinded coil parallely to stock RR (Charging part) to get DC output which was previously meant for battery charging to run the relay. Relay is connected between Battery & BCU. Coil will give output parallely to APE RR & stock BCU. I have not kept any switch between these modified harness as switching will be done automatically. I have not connected it to my byke as the Gasket of Stator cover is not available. If it gets damaged while removing the cover than I cannot fit it again till I get a new Gasket.
My concern is there any issue if I connect the output of Coil parallely with two RRs. In my case stock RR will work only for the puny relay. presently H/L (OSRAM Nightbreaker 60/55) is connected via relay. But sometimes having drainage issue when night driving is for longer hours.
Waiting to hear from all DIY XBHPians if any more mods required. Also please let me know the steps to check for any issues at different level. I will post the diagram & pics later.
