[w202td]

hi
just started my car this morning coming to work and its doing a very strange thing
the lights on the instrument cluster are intermittently blinking
and the temp and rpm gauge drops to zero
the rad,esp,glow etc all lights come on then dissapear
is this the beginings of a alternator prob?
