2000 Honda Accord No communication in the car

There is nothing wrong with fuse # 6 and yes, it is used for so many components.

The alternator charging indicator test does not require any special equipments.

I have sent the files to you again jut in case it was missed out. Let meknow the outcome.

This seems to be a fault with the charging indicator circuit and since the test indicates all the wiring are in good order and to replace the alternator, then most likely the alternator is faulty.

As I mentioned earlier, bench test only test the alternator performance, it can pass but the charge indicator ciruit fails because the bench test do not provide any test for it.

Get another alternator to test.

When the alternator chage indicator circuit malfunctions, it can glow dimly and that is the reason the alternator is recomended to be replaced as per the test.

It is possible for it to occur. As you have performed all the test outlined and it indicates the alternator is the cause so we shold get a replacement alternator to avoid wasting time on diagnosing and getting nowhere.

All the more the alternator is faulty.

There is the main wire from the battery via fuse box to the alternator main terminal.

If both alternators are new then the possibility is low bt if it is a rebuilt, I would not discount the possibility.

Keep me updated. I would like to know the actual cause too.

The rectifier can be tested but not the voltage regulator.

RECTIFIER
Check for continuity in each direction, between the B terminal "A" and P terminals "B", and between the E terminal "C" and P terminals of each diode pair. See Fig. 12. All diodes should have continuity in only one direction. Because the rectifier diodes are designed to allow current to pass in only one direction, and the rectifier is made up of 8 diodes (4 pairs) (6 diodes (3 pairs) for 2000-03 models), you must test each diode in both directions for continuity with an ohmmeter that has diode checking capability: a total of 16 checks (12 checks for 2000-03 models). If any diode is faulty, replace the rectifier assembly (Diodes are not available separately). If all the diodes are OK, go to BRUSHES inspection.

The wire is linked to the Driver's Multiplex control unit and grounding it can cause the symptoms described.

Did you try grounding the wire and then only turning the ignition switch on? If yes and the indicators turns off after 2 seconds, then the circuit is ok, if not you might have a fault with the multoplex control unit.

However the hazard lights should not come on.
