My '05 FS650C came with a wiring harness that has two female sockets under the number plate. One would accept three prongs and the other, two prongs. There is also a female two prong socket under the tank that appears to be for a tail light connection. I want to connect up standard 12vdc head and tail lights for the street and have regular Husaberg units taken off my '05 FE550e.
Now, here's where things get wierd: With the engine stopped, I measure 12.5 vdc across all three sockets. I also measure 27.0 vac at these same points and when I start the engine these readings stay the same, except one socket on the three prong plug actually increses with rpm up to 60 vac! How can these sockets read both vdc and vac especially when the engine is stopped. I always thought you had to have the engine running in order to generate alternating current. Does anyone know what is needed to install a head and tail light on this bike? Connecting standard 12vdc bulbs work fine at rest with the engine stopped, but blow the filiments shortly after starting the engine. With 27 vac on tap, it's no wonder!
