Please please please, get a remanned or new Denso. Do not buy anything else. You WILL regret it.
Unless you love electrical quirks and replacing alternators, get a Denso.
I had this issue with my 2013 civic. Was replacing the battery about every 12-18 months. All the systems tested fine but the problem was fixed when I finally replaced the alternator.
Put the desno in fixed all my problems
I recently replaced my alternator on my 07 SI. Very easy and there are YouTube videos on it. Good time to replace serpentine belt if its cracked at all too. I went with a used OEM unit from eBay from a 2010 crv and it's been working great.
I tried a Bosch reman from Rockauto on my Civic. Lasted about two years then the rear bearing starting squeaking.
Get a denso reman or be prepared to replace it again in a year.
Horrible mistake with the aftermarket alternator. You likely will need to redo the job really soon.
I would like to add we had to replace my sisters 2016 Honda civic alternator as well and the car rejected the Part we bought. All the lights on the dashboard were on like a Christmas tree.
I think it may be the alternator to be honest because I’ve had one headlight burn out trunk latch inside the car stopped working but the key fob works window button not work properly in one instance, so-called battery wasn’t good when I just had it replaced less than six months ago. Recently they told me that it was my battery this whole time and within two weeks the lights were back on my dashboard.
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.
