I bought a new battery about 4 months ago and several days ago had it checked and the battery is good. I was going somewhere and the car wouldn't start. This is the 2nd time this in 4 months I had to have it jumped. Went to Auto Zone and they charged it fully as it was at about 78% and tested alternator, both are good. So, apparently there is a slow battery drain. I looked under the hood and trunk to see if a light stayed on and noticed that if the car is locked, the security light stays on. If it is unlocked it goes off. So, I suspect that is my battery drain. I have had to leave my car unlocked for a couple of days. Each of those days, I drove it around for 15 minutes and today it seems to start up like normal.
Could this be a fuse problem or something more serious?
