I know there are lots of threads on here talking about this same issue and they pretty much all say the same thing, either new battery or new alternator. The light came on from the previous owner. Who replaced the battery and the alternator. I got hurt at work after purchasing the car and it sat for a few weeks. The battery went bad but the alternator was still charging it a bit. I took it to Honda for a diagnosis to figure out exactly what was wrong before I started slapping new parts on. They said the alternator was bad and of course my battery. So I spent $500 on both a remanufactured alternator ("new" with lifetime warranty) and a new battery. The light is currently still on. I know my new parts fixed the problem because my battery is staying at 12.somthing volts after days of letting the car sit. Plus, when the car is running the battery voltage stays a steady high 12's full load (AC and headlights on) and low 13's (when I turn the AC and lights back off) meaning the alternator is doing its job. The belt is tight and it's not slipping. I've checked every fuse under the hood and under the dash. None are blown nor have been blown. I've checked all components under the hood to make sure grounding was good with continuity tests. The only issues I've had are, the trunk quit working which I believe is the actuator. I can still unlock it inside the trunk but we all know if you do this it never locks. So that's not an option. Then about 6 months ago I threw a check engine light for an 02 sensor. I cleared the light. A few days later threw a light again, this time for a secondary 02 sensor. I cleared it and it's been gone every since. I checked the wires under the car on both 02 senors to check for bare copper and shorting issues as stated before on past threads. They were all fine. I still haven't replaced the sensors since the light hasn't came back on. But they're in my shopping cart. I also have a trunk actuator in the cart as well to be purchased. Tomorrow I'm going to be doing a load test on every fuse in the car while it's off to see if anything is pulling while the car is off. However, if anything was pulling enough to make my light stay on, the battery would be draining. Which it's not. Also going to test for shorts on all the fuses as well. Besides checking for shorts does anyone know how to get the battery light off if everything checks out to be fine? There's also a relay according to the wire diagram under the hood in the fuse box that I have to check that's tied into the alternator. Any help or advice would be awesome.
Thanks in advance!
