Often times you need to kick up the rpms upon initially starting the
vehicle to to get the alternator to start producing current.  If this is
the case in your vehicle, the battery idiot light on your cluster will
also be illuminated until the alternator starts working.  Double check to
make sure that the idiot light on your cluster is not on, then look for
voltage at the blue wire.
