Megane Warning Light

I have a warning light that flashes below 1200 revs. My fan belt recently snapped so i assumed that the light was something to do with the alternator not chargin. i have had the fan belt done and though after a good drive the light would go off but it hasnt. The light is yellow and looks something like zig zag line of M.

can someone help

That is to warn you that you have a fault in the electrical system of the engine.
