1980 XJ650 Maxium, 25K+ miles. Electrical system all stock sans a new fuse box. A question to those who have experience here. I'll use the polling function, but would like to hear from all who have been there done this.. To replace the brushes or not? I have had no charging system issues since acquiring this bike Sept 2015, and have since put 20K+ miles on the machine. I just discovered the owners manual says to replace the alternator brushes at 10K. Say what!! I have never touched the alternator cover, period. System has powered a heated riding jacket on many cool ride days. Right now, with engine at 2200 rpm, jacket on high temp setting, all running lights burning, voltage shows 14.2 at the battery. Lucky maybe? But, riding season is almost here and that is no time for repairs - only pre-ride inspections, bug removal, and oil changes. Getting ready to do my seasonal bike prep ( yes Len you will be hearing from me soon!) so does anyone have feedback /experience with very long brush life? Thanks, all.
