Electrical issue battery dies slowly

Having a slight issue. Something keeps drawing my battery down. If I leave it for more than a few days battery is completely drained. Replaced battery and starter relay. Any ideas?.... Thanks

How I chase these down. Get a good Multimeter and set it to amps and place it between the positive lead and the positive post of the battery. See how much of a draw you are getting. Start pulling fuses until the draw drops to almost nothing. When that happens replace the fuse and start chasing that circuit. Depending on the circuit you will need to either pull plugs or connectors until you find the short. Good Luck plan on a Weekend at least to do this.

Have an aftermarket stereo? Had a friends car do that to me last summer. He drove it for a month everyday, left
It for a week and it wouldn't start so he kept pulling battery lead so it wouldn't kill the battery. Cant remember how now but we traced it to the head unit. Some genius cut the wiring harness and tapped into everything live. So head unit was always lit up. Never noticed cause he pulled the faceplate off. Needless to say, got a new plug, solder, solder , solder, shrink tube and got an adapter harness now it works good.

Well I always manually turn off all electronic devices in the car before i turn it off (a/c, stereo, etc...etc..) but use the multi meter to check the votage of the alternator. The 1st reply to the thread was a good idea for sure, and that's what I do too.

Alternator check. The voltage from the alternator should be around 14 to 15 volts but the only way to know for sure is to take it to an auto store and have them do a load check. For a constant current draw which was the original question the way I described it in the first post is the best way to find it for sure. I have found bad grounds bad plugs on trailer plugs bad stereos tail lights etc this way it has never let me down.
