Tapping Fuse Box Causing Problems

I was installing a standalone DVD player from Audiovox and decided to tap an accessory fuse opening in the fuse box for switched and constant power. Everything went as planned, made sure wiring was correct and not touching anything else, checked grounds and even turned the car ignition switch to ACC for less than 30 secs to see if the standby light on the player would turn on, everything was working.

10 minutes later when I went to take the car out of the garage it wouldn’t start, this being said I drove it into the garage without any problems a couple hours prior. For some reason the battery drained every 30 minutes and would need a jump start to get going. I immediately disconnected the fuse tap to see if that would help. Still drained, so I decided to get a new battery and when it was installed everything worked fine. I am very hesitant to put the tap back in does anyone possibly know what happened? Thanks
