Have a Honda Question? Ask a Honda Repair Expert.
Have you checked what the actual voltage at the battery is while its idling?
Have you done any testing yourself or you have been taking it in for diagnosing?
I'm going to look over a few wiring diagrams and I will get back to you.
Would you happen to know what engine size you have, 2.4 or 3.0?
Other than the light being on do you have any issues with the battery dying.
