just got back from a short trip into the catskills
turned my car off and a humming is still coming from the engine
a rather loud humming

pop the hood and it's coming from the abs unit
sounds like a motor running or something
only it's very loud

i havent shut my car off yet
and i cant call my mechanic since it's sunday

anybody have any ideas?

by morning i think i'll have a drained battery if i cant stop it
