Re: 2000 Elantra Alarm Light and a Draining Battery

by "Owl" <NOSPAMYO@[EMAIL PROTECTED] > Jun 15, 2008 at 07:55 AM

Advance swore up and down the battery was fine and refused to honor the
warranty.  Took it to auto zone and just told them to pull it out and give
me a new one.  Drove home fine.  Went to get back in the car I open the
door
and bam alarm goes off.  Apparently now that I have a new fully charged
battery my alarm now has enough power to just go off on it's own non stop
and wake the neighbors.  I liked it better when it was silently sucking my
battery dry.  I just disconnected the battery to stop it, I'm going to
have
to have it towed to the dealer now as I can't even drive it, it wasn't a
bad
battery :(
