Try a Denso alternator. Somtimes those cheap ones at the auto stores just dont last.
Owner reviews for alternator
The same thing happened to me. 2012 Toyota Camry LE. The car never asked for anything other than brakes and tires. At 120000 my alternator went out on the beginning of a vacation trip.
Volvo tech here, Bosch. Just replace the whole thing, it's not worth doing the brush job only to find that you should've just done the whole thing first.
I would suggest Denso for the Honda. With a high amp usage like an Odyssey, anything, but Denso will cause the battery light to be on intermittently.
You can get a remanufactured Denso (OE) for that car: it's probably the most cost-effective option.
I ordered the genuine Bosch alternator for not even 300 bucks and installed it myself for him still good a year or so later and it was a very easy job
I just did alternator on my wife’s Toyota. Paid $340 for it and did it myself in 10min. All I did was google for the parts store that had it in hand. YouTube how to remove and install.
I want to replace the alternator myself, but I can't find where to get OEM parts for a reasonable price. The dealership is charging $340 for the part and the best I can find is this [Bosch alternator](https://www.amazon.com/dp/B001C64QHE/ref=wl_it_dp_o_pC_S_ttl?_encoding=UTF8&colid=TXMF4LHVIWCE&coliid=IN63F3OG0M77W) on Amazon which they state is new, but it seems like all Bosch alternators are remanufactured. Why is it so damn complicated to find high-quality replacement alternators?!
I once went through 3 alternators in 2 days from the Ford dealer on one job.
I when my original alternator failed in my 540i/6, the replacement rebuilt Bosch unit would produce 13.5-13.7v for a while after the car had warmed up, then would gradually fall to less than battery voltage. Running the A/C and revving the engine at stoplights would keep the battery light from flickering, but eventually, it would show full symptoms of a dead charging system.
