What is the sensor that causes the battery light to come on? My battery light will flicker on for a few seconds after driving for about 10 minutes. According to the manual, the battery light coming on only indicates that the battery is not being recharged so this would indicate a battery or alternator problem. Is it at all possible that the starter wiring or the starter relay could be causing a battery light to come on?

We're missing very important information: What year vehicle? What engine? How many miles? How old is the battery?
It's not likely that the starter relay or starter wiring is the problem. It is likely that the battery and/or the serpentine belt is the problem. OEM alternators last 200,000+ miles.
Of course the first thing to check would be the battery cable clamps - remove and clean the clamps & posts. Check/clean the body side of the negative wire too.

My guess: the alternator brushes have worn out.

As mentioned, do the cheap things first, as with any repair.
Clean, inspect the battery terminals, also check the alternator charge cable for corrosion. Replace if one or more are bad.
Test the voltage at the alternator and the battery, see if they are in spec.
Inspect and replace the belt
If the battery tests bad, replace it.

Had the same thing happen to me, turned out to be corrosion in the middle of the ground cable (neg. cable on the battery). Replaced & problem solved. If you have the 4 cyl. it would be best to upgrade the cable from the 8 ga. to the 4 ga. that came on the V6. Make sure no corrosion is on the ground terminal.

Mine failed at 139,000 miles. Battery light came on with the bad alternator. An offbrand reman alternator lasted two weeks before the battery light returned and it was putting out 11.9V. I then got the original OEM alternator rebuilt and so far so good. I recommend you get someone to rebuild your OEM alternator if it is indeed bad, or buy another OEM alternator.

My OEM alternator was still going strong @ 400K, thought it was time to replace & bought a Bosch which lasted about 2 yrs. OEM for starters & alternators.
You saying, you went 400K on OEM alternator w/o any issues? or lights?

400K on orig. alternator, 300K on orig. water pump, no issues on either. Light came on a couple times because of the battery.

Battery Light Flickering 2005 Accord EX
I've replaced the negative ground cable and alternator on my 2005 Accord EX 2.4L and my battery light keeps flickering on from time to time. I've posted about this before because about a month ago I was cruising down the road and the battery light came on and next thing I know my starter burned up while I was cruising along. Replaced the starter too but just can't seem to figure out why the battery light keeps coming on......any advice would be appreciated......Thanks!

I've swapped out an alternator (cheap Pep Boys house brand) on a Toyota, only to have the battery light dimly lit thereafter. It was lifetime warranty and owner was in a rush, so she drove it that way till it failed again, 6 months later.

original alternator failed. Daughter had out-of-town repair where they installed an aftermarket reman alt. I had her keep the bad alt and pay the core charge.
A few weeks later, the reman alt started giving low voltage output (and battery light).
In mean time, I had the original alternator rebuilt at a reputable place in town and installed it myself when the reman started acting up. No battery light or voltage issues since then.

Merged. No need to create another thread for the same problem just because you never came back to give an update or answer questions in post #2.
