Hello all, I have read a bunch of charging issues, but my question was not addresed with other peoples problems. When I start up the bike first thing in the morning, at idle, charge light is on, above 1100 rpm, it goes off. After riding for about 10 minutes, the charge light stays off at idle. about an hour later if I start it up, same thing. My landlord here in Germany says that is normal. I dunno, I am just verifying. All contacts were cleaned, new battery, tested voltage, it is good. it does not undercharge or overcharge, it fluctuates with different RPM but does not over charge or undercharge. there is no key off battery drain. I know there are alot of more BMW experienced people than I, I am a descent mechanic, but not familiar with BMW bikes, but not afraid to tackle repairs or disassembly.
