Re: BMW /5 toaster cafe-- stator and diode board upgrade
Hey, guys. I went through this as well. I removed the gauges all together on my bike and wanted to find a quick fix. Did a lot of reading on the topic here:
http://bmwmotorcycletech.info/genlampresistor.htm
But in further reading and discussion on the ADV forum I was lead to this handy lil' kit:
http://www.motoelekt.com/genlightacc.htm
$3.50 well spent and the bike keeps a charge. The logical reasoning in keeping a generator light (or wiring one in if you go with another set of gauges) in addition to installing the jumper is.....
"A dim lamp at a relatively modest to high rpm usually means some sort of corrosion at some connector(s), or a bad rotor or brushes. A bad battery can also cause the alternator to produce a very large output in such a way that the lamp might glow dimly. A bright lamp at riding rpm USUALLY means an open or shorted rotor or bad regulator, or a bad diode board, and likely there is no charging (no alternator output) at all."
Hope that info helps too.
