I had the same issue with my ST as others have reported: a stalled bike with no change in voltage as the engine revs: obviously a charging system issue. Who knew that the throttle body and alternator would be so hard to get out? But I finally removed it and found that the rotor wiring was open. I'll get a new alternator but wanted to ask for some wisdom from the assembled experts: what else should I fix or replace while I've got the entire top of the bike apart? I have a 2003 with ~116,000 miles on the clock. Maintenance that I've done in the past (thanks to the coolant leak threads):
Replaced the bigger coolant hoses a few years ago to stop a mystery coolant leak
Put those fancy hose clamps on the bigger hoses (still smell coolant when fans kick on)
Replaced the thermostat with a Honda OEM
I never want to open up the bike this far again, so this is my one chance. What else should I do while I'm staring down into the abyss?
