I'm posting this in case someone else has a similar problem. About a yr
ago, my '99 Accent would crank slowly if left for more than 2 days. I had
both the battery and alternator checked and they were ok. Using my
multimeter I found out I had a power off current drain of 250ma through
the ECU circuit. Everything ran fine with the car except the current
drain, so the short term fix was to pull the ECU fuse under the hood when
not using the car.
  It started to bug me so I traced the circuits attached to the ECU fuse,
and this includes the alternator sensing wire. I disconnected the alt. plug
and the drain went to almost zero. I replaced the alternate and all is
well.
  Even though the alternator checked out OK, it really wasn't. Maybe
someone else has a similar experience.
