2003 Accord Euro Electrical problems

Hi guys my friend is having a major issue with his 2003 Honda Accord Euro. This is his story:

"The other day I was driving along and realised my airbag light was on. I pulled over in a side street and turned off they car then back on to see if that fixed the problem. However the car would not start as if the battery was dead. I managed to kick start it and my airbag light would then only come on when the motor was not revving, ie at a complete stop or with my clutch in. I thought my battery might have been dead so I continued driving to charge it up. While travelling at 70km/h it began to rain heavily so I turned my lights on. The instant I did this all electronics lost power. My dash speedometer shot to 0km/h, fuel gage, rev gage and stereo all turned off. Turning off my lights restored power to all components."

I have suggested changing the alternator, Any suggestions on what it could be?

I had a similar problem where my electricals went out whilst driving, it could be the battery and/or alternator, but my problem stemmed from some wiring issues under the fuse box...
hopefully it's something minor...test out the alternator / battery to make sure they're the issue or not...good luck! keep us posted

This seems to be a recurring problem with the 2003 model.

Try changing the grounding cable. It worked for me when I had a similar problem. Either that or there are a few other things that have been suggested:

- Ignition relay, switch, barrell
- Alternator (or just the bushes)
- Alternator pulley to belt drive
- Multiplex bus
- Regulator
- Fuses (the alternator fuse is, I believe, 85A and can sometimes crack and be faulty without this being obvious)

Honda said they thought it was my "non-Honda" bluetooth unit that was causing the problem and that they would have to take the radio out so it would cost $286AUD. They said they weren't sure if that would fix it so the next thing to do would be to change the ECU and that would cost $2000AUD.

Very glad I came onto the forums and found out a lot before giving the go ahead to Honda.

This thread was for my car. Cost me $900 for a reconditioned one from Honda. That included diagnostics, installation and all that jazz. Probably got ripped off but I needed it done fairly quickly. From memory they quoted roughly $2000 for a brand new one. I know another accord euro owner who had the same problem and got his done for $600. Must be a common problem.
