I have a street legal "DK" version of the BRP bought in Japan. The "DK" electrical system has a higher output stator and a small regulator/rectifier and condensor that aparently (from my read of the diagram) only powers the brake light, there is no battery. I need a power source for my bar mounted 12V GPS. When I wire it into the power off the condensor/rectifier it works fine until I hit the brakes and then it loses all power. What could solve this problem short of adding a battery and charging system (I hate to add that much weight)? Would a bigger condensor work? Thanks to anyone who can help.
