got a 300zx (z31)

last night on the way home i noticed my cars lights flashing, i.e. the Intrument bezel lights, (idiot lights) were flashing every now and then and my amps were at about 10ish..(usually at 14)

it automaticlly stopped and my amps went back to 12ish.

today start my car, does the same thing only it doesnt stop.. im now 45 minnutes away from my house, amps were shoiwng 10ish.. car WILL NOT turn over...
