The alternator on my bike is fine but when I saw the number of articles about this item on the forum I went and bought a used one to rebuild and keep as a back up spare.
The accessing and removal of the alternator is not an issue to me and for those who think that this aspect of replacing the alternator is a job too far then think again. The biggest issue for all of us as this bike model ages is the piracy of Honda in its pricing of parts for this alternator. I'm so glad I obtained a used unit as today 24th January 2024 in the UK Honda bless them want £1964.00 for a new complete unit. The regulator retails for £415.51 and the rectifier which is very hard to find is yours for £346.96. Since these parts are the items which commonly fail it would seem to make either buying a new alternator or replacement parts financially prohibitive making the bike a scrapper. DO NOT DESPAIR.
The rotor bearings are relatively inexpensive. The rectifier can purchased from CARMO ELECTRONICS in the Netherlands, currently at just under £60. This seems to be the only source for this unit at present as all my extensive searching even on Denso has come up with nothing but £60 is better than the kick in the teeth that Honda would give you. The regulator is common to a number of Triumph alternators and can be obtained from both Carmo electronics and ELECTREX in Oxford UK also for around £60.
It IS worth taking the time to rebuild your own alternator. Do it!
