It could mean a few things. There's a voltage range in which that light stays off, which seems to be between 11.5v and 14.5v. The light comes on when you're either above or below that range. Start by checking the alternator fuse. If that's good, and it almost always is, do a voltage test. Too low and the alternator is probably bad; too high and the voltage regulator went out. (Which is basically the same thing, since the VR is inside the alternator case.) Check to see if alternator is charging battery. With volt meter connect to battery and vehicle not running check voltage - start vehicle and observe volt meter should be around 14.2 volts - if no different running or not or if lower with vehicle running alternator is not charging battery and should be replaced. If alternator functioning properly it is probably just the "trigger" wire on alternator.
Dead cell in the battery requiring it be replaced or something is on pulling power from the battery. Some light or relay.
there is usually a fuse box next to the battery under the bonnet
The light is on because the alternator is not putting out the required voltage. Either the belt is broken, loose, or the alternator is defective.

The yellow radiator light on your Honda Accord is an indicator of low coolant in the radiator. The red radiator warning light is an indication of the engine overheating.
Check to see that the belt is tight on the alternator.If it is, check the stator wire it may be loose.
It means something is wrong with your charging system. Can be a loose of corroded battery cable, defective alternator or a battery with a dead short.
If you are 100% sure the battery and alternator are good and the battery is loosing it's charge then something is on pulling power from the battery. Can be any light or any relay on the vehicle.
Yes it has. I have a 09 Accord coupe.
