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 would get a better alternator. Denso (reman or new is fine) seems to be the only one that can take the high electrical demand of the Odyssey.
Denso alternators are the best. Denso makes great products. I do a lot of side work on Hondas and I am so thankful Denso offers their stuff outside of the dealership. I replace alternators, a/c compressors, oxygen sensors, etc all the time and I choose Denso bc it's basically the same exact part you receive in a Honda box but for half the price.
Get the Bosch, including the warranty from them, and be done.
Bosch has a support site that shows what alternators they recommend for your VIN number. AL20X (65A) and AL172X (65A) are the two Bosch shows. However most of us know the original was a 90A unit AL30X.
If the alternator is OEM, replace it, because is close to the exhaust manifold, it will fail sooner than later.
After getting mine rebuilt 3 times and still having the same problem, I ended up getting a Bosch factory rebuilt one. Cost-wise I don’t think it was significantly more than one rebuilt by a shonky auto electrician and in the long run would have been cheaper.
Mine was my alternator. Never had battery issues but once I replaced it with a new bosch all the electrical gremlins the car had went away.
I bought a Bosch rebuilt alternator from ECStuning and installed it last night. The light however has stayed on.
I replaced my original alternator (which is also denso out of the factory) with a brand new denso alternator. Should be the exact same thing as the factory alt. It's not working at all. Battery is not staying charged. Had a complete diagnostic done by Honda and they said it is the alt. Kinda disappointed I waisted $700.
