This has been bugging me for a while and I have no idea what is going on?

When I start the car up in the morning the ignition light goes off like it should do.

As soon as I put my foot on the accelerator the light comes back on.

I'm guessing the alternator's got issues but I can't really see anything wrong.

Mind you i haven't looked properly at it but from a quick look it all seems fine?

Does anyone know why this would be happening?

Thanks!
