I am not sure what year your odyssey is, but I know you can go to rockauto.com and find the Denso remanufactured alternator that is the best one to get.
All the others tend to go bad within a year or less.
Ordered a denso reman alt for my 08 tsx last year and it fixed charging system issues I kept having with aftermarket alternators:)
I think the Denso alternator is the ONLY remanufactured alternator I will buy. I've been burned too many times trying other remanufactured brands.
But I typically always buy NEW alternators from RockAuto. Sometimes the bearing is bad out of the box so I have to return it and get another. But when I get a quiet one, they seem to work fine. Nice and steady voltage output around 14.3V
Just buy a reman denso
Ok, so it's a toyota so odds are it's a denso or denso style alternator. I used to rebuild Alternators, you will need access to test certain parts like the regulator, or diode trio, or the windings to see where it's failing.
Personally I’d go with a Denso 27060‑50230. More expensive but it’s an OE part not third party. The one in your car was originally a Denso and it lasted almost 30 years, right?
This year, I needed my (original) alternator replaced.
I just did mine last week with Denso remanufactured , snapped the bolt and had to replaced the pulley tensioner too ????
No, don't get the denso remanufactured, because I got mine and it failed right out of the box.
The Denso branded remanufactured alternator arrived from Rock Auto with a broken plastic socket. I arranged a return and replacement, but the second unit also arrived with the exact same damage. I believe the issue is with Denso's factory packaging, as the alternator is placed socket-down without cushioning. I returned the second replacement for a refund.
