Failing alternators

Post by bsa59 »



I have an 01 Gl1800 trike. Love it , for two years now it's been great, until coming out of west virginia early this summer when the alternator fried. Been thru two more since, all professionally installed .had wiring checked over and reportedly the relays also, including looking for bared wiring touching the frame. Get the bike back, drive about 25-30 miles and i'm in the same situation (stranded again) Anybody have any ideas or similar experiences? Please help. Roger

Cheap chinese alternators!
I went through two of them here. Only lasted about 10k each.
I finally located a original Honda Hitachi alternator. (at a heart stopping price!)
That one has been fine for two years now.
It appears that all the aftermarket alternators out there are coming from
the same crappy chinese suppliers, no matter whose name is on them.
Good luck.

What has been the normal life of an alternator? I normally never keep motorcycles that long but this is my first goldwing and I might keep it a lot longer. Is some years better than others? Mine is a 2016

2016 wings are great year. My 07 with 118k miles has the original alternator with zero issues. I do have spare brushes and bearings on the shelf and I'm tempted to have them replaced but as I said I'm having zero issues with it.

My 2016 has over 40k on it now. Had 10k when I bought it couple years ago. Had some issues with it that had to be repaired but nothing yet left me stranded in the middle of nowhere. Being stranded is my biggest concern with anything I own. Other than motorcycles everything I own is 20-50 years old.

Be sure to only use ones that come in Honda packaging. Lots of cheap stuff sold as "like new OEMs." Almost all others fail within the first year. Real Honda ones come in Honda packaging.

Alternators fail from plugged fins from riding in dusty environments, causing over heating rather than cooling and the regulator fails.

Generally, OEM alternators at least last a decade or two. Aftermarket ones usually last days, weeks, or possibly a few months.

Did you put in aftermarket alternators or did you buy from Honda new OEM($600-$800)

My 08 alternator lasted until 158,000 miles 2 years ago. I didn't know about keeping it blown out so the fins are clean to allow proper cooling. Keep your alternator fins clean and you should get even more miles.

What would be the best way to clean out the alternator ? Blow it out from the inside out ? Can you do it without taking the alternator out ? Can you clean it with a water hose ?
