2002 honda accord battery charging issues?

I have a Honda accord 2002, 2.3, 4 cyl. It was wrecked within in the last few months on the front, passenger side. I have been having serious electrical issues and dumping money into it like its my job. The battery tests good. My alternator tests bad when it is in the vehicle, but when I took it out and tested it on the machine 3 times it tested good. My cables and terminals are good. I have a 1.55 amp drain, my alternator will not charge my battery, I have been told that the 2002 Honda accord has a computer controlled charging system, which I have been researching and can't find anything on this topic, although he said it could potentially be the problem and the cause of the drain. I can't afford a certified shop at this time. I have no idea what to do next, any help is appreciated.

When you test the alternator, it has to be tested in the car, with all the lights/accessories on, at 2500 rpm in order to get an accurate reading. It needs to be putting out enough amperage to charge the battery and registering the right voltage. Just because the alternator has the ability to test ok does not mean that it is ok.

You should have the vehicle scanned with a diagnostic computer, this will be able to find any faults with the computer controlled charging system. How did you have the alternator tested on the vehicle? Did you use a multimeter to check that it is outputting at least 13V DC (Direct Current) remember that a alternator will produce AC (Alternating Current) and a rectifier pack will convert this AC to DC otherwise if the rectifier pack fails then the alternator will output AC voltage which the battery will not except, if the alternator is putting out DC voltage then you may have a problem with the computer controlled side.

An ashtray light will draw 1.5 amps. That is really nothing. Autozone has that wiring diagram info. Register at autozone.com, put in your year, make, model & engine size, then click on repair info, chassis wiring, wiring diagrams, or just wiring diagrams.

A good electrical mechanic should remove each fuse, one at a time and test for a *parasitic amperage draw.

Well you have already dumped lots of money into this and you still have the problem. You would have been better off taking it to a professional shop in the first place. But 20/20 is hindsight. Check all the wiring going from the alternator to the battery. You have to find out why the alternator is not working in the vehicle. Are you sure it is hooked up correctly? The 1.55 amp drain sounds like a relay that is stuck closed. A light would not cause that much drain. Check all the relays. I would advise you not to throw any more money at it. If you are unable to repair it yourself, take it to a pro who will repair it.
