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, could potentially be the problem and the cause of the drain. I can not afford a certified shop at this time. I have no idea what to do next, any help is appreciated.

 

maybe the charging signal wire is not sending signal

 

Was the fuse panel damaged in the wreck. It could be a loose connection there, otherwise test voltage coming from the alternator to see how many volts are going back to the battery. I believe there is also a 100a fuse between the alternator and the battery, if so definitely check that

 

Can you isolate which circuit it is? I assume you have an amp meter, as you know how much of a current draw there is. Install it, in between your negative battery post and cable, then start pulling fuses. If it is only one circuit, when you find it, teh draw will drop to closer to zero(Assuming all lights, radio and everything is off) Once you know which circuit it is, that makes troubleshooting a little easier.

here you go

 

here is this one too

 

I found the problem it was a faulty ELD. Preventing my alternator from charging, it starting throwing out multiple check engine codes. These dual charge systems are all new to me. Thanks a lot for any input and concern everyone.

 

I had 3 transmission codes, 02 censor code, and my condenser and cooling fan stopped working. As well as the additional epic p1298 code all came up shortly after I made this post.

 

Thank God this is over. At least I have a new alternator and battery, as well a lot of electrical accessories :D
