Beware of cheap aftermarket junk. I would only get an OEM or denso alternator.
Or since Denso is the OEM, you could get a remanufactured one at [NAPA](https://www.napaonline.com/en/p/DEN2105000) or [RockAuto](https://www.rockauto.com/en/parts/denso,2105000,alternator+/+generator,2412), but it looks like they're out of stock. I would not trust the cheaper remanufactured ones that are made by the other brands. Denso is reliable, and I'd trust their reman parts, if you decide to go the reman route.
But try to get denso one or oem. Aftermarket ones tend to not last a long time.
I ordered a new denso online then had a mobile mechanic come install it for me in my garage.
Buy a Denso or OEM Honda alternator if you want to do the job once. The cheap Chinese-made brands and auto-parts store brands will die within a year or two. Ask me how I know!
I went through 3 OEM Denso's before going with an OE (Land Rover stamped) Denso. Presto! No more charging light.
Good job OP. I had the battery light turning on/off for months and figured it was the alternator(newish battery). Was about to purchase a reman Denso for $160, but glad I found a video of Timmy the Toolman on youtube before purchasing and went this route. Pretty easy and straightforward.
Go for a Denso alternator if they have it.
I suggest either getting your OEM DENSO alternator rebuilt at a shop (costs like $60?) or picking up a low mileage used DENSO alternator from a junk yard (or eBay). The Amazon new ones are probably junk and can cause trouble down the line.
Denso is usually one of the top ones, if they've tanked in quality I shudder to think how bad oem GM, and mopar/stellantis has gotten. I still have nightmares from absolute shit quality of GM parts, alternators and starters barely lasted over a year.
