Alternator OEM FORD or Denso

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 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.

If the alternator is OEM, replace it, because is close to the exhaust manifold, it will fail sooner than later.

If you are replacing the alternator, strongly recommend using only Honda dealer sold remanufactured alternators (probably Denso) or an aftermarket Denso brand remanufactured alternator. Lots of problems reported with other brands.

I have experienced my share of faulty Ford alternators from the chain stores. I now get OEM from Ford. Yes, they are expensive but I have better things to do than replace month old alternators constantly.

If you’re gonna go through the effort of replacing the alternator, do NOT get cheap shit. Get a new/remanufactured Denso alternator.

Denso alternator is my go to choice for that vehicle.

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.
