BMW R100GSPD alternator lamp comes on early.
Nov 1994 model, 150 000 kms. Never had any work done to the electricals (so I am worried that they might soon be due). Up until now the alternator lamp came on at just below idle revs, 800rpm. Now it comes on at 1500rpm, and does not go out until 2000rpm. Battery is 2yo and seems good. Bike starts easy. Voltage increases with revs. Is this new development something to worry about? For the record I blew a rear tail light at the same time this happened.
