like an EMS light or
something like that I
don't know what it
means people tell me it
could be my alternator
but I'm not sure could
someone please help

From your description alternator. Put voltmeter on battery with car off. 12.4 volts or higher? Keep meter on battery while someone else starts car. Keep your eyes on meter voltage. Does battery go below 10V? If so bad battery. Once/if it starts, what is voltage while it is running? 13.5 - 14.8? Too low or too high and you have a bad alternator. Also during this test turn on some high drain components to see if regulator holds voltage in this range it might go down as much as 1/2 a volt but not more. Absolute lowest voltage with circuits energized should be 13.2 volts.
