Alternator OEM Honda or AC DELCO

Honda uses great parts. They're expensive though. I had to buy the OEM alternator for my CRV from the dealer (because that was the only one I could get in one day) and it was 700 bucks

I always get AC Delco from RockAuto... never had one bad out of the box... Can't really speak to any other brands.

I had a Honda Odyssey do this for years. Finally took to Battery Plus. They checked my battery at the time (which was not having issues…yet) which they said was good. On a lark i asked if their device could tell if the alternator was okay. He said yes, did something on the meter, and then showed me on the screen the alternator showed “errors”. I had the alternator replaced and the dead batteries stopped happening.

In my experience, it’s most likely the alternator, I’ve replaced so many I’ve lost count.

My local mechanic put a new alternator in my older Accord late last year. It was around $550, including a new serpentine belt.

Honda OEM alternator

I\u2019ve had an ac delco alternator from rock auto in my Honda Fit for 7 years now.

I just had a new alternator put in 2 months ago (3k miles ago) at a different shop. Could all this be caused by a bad alternator?

The issue you can run into is most common vehicle alternators are light duty at best. Lets say its a 100 amp alt, don't pull more than 40 amps continuous. A great example is the AC Delco 10si alternator. Loads of cheap knock offs and copies of that alternator all claiming crazy high amperage but none list the duty cycle. The 10si frame is designed for 40 amps of power and the heat that creates. You might be able to get a little more cooling with a better fan but you won't get 100+ amps out of one.

Reminds me of my old mans '96 Honda Civic hatch. 6 hours to do the swap (4.5 out and 1.5 with a dinner break in) in his yard using mallets and a fucking chisel to get the old one out.
