Battery Drain Problem/Questions

[daak]

Okay I'm getting a slow battery drain since installing my vintage "Sony Minidisc Receiver mdx c7900" into an 04 xterra. I takes weeks to drain the battery to the point where the vehicle wont turn over. I removed the receiver until I can identify the drain on the battery (95% sure its the receiver). I'm sure of all my speaker connections, its just the other power and misc connections (in the photos) I'm not sure about.

Can any problems be seen from the attached images?

Would leaving the faceplate on drain the battery?

Any electrical issues related to that model receiver?

If anyone needs better pictures or labels, let me know.

Thanks.

I had that problem once, and the problem was that the accessory and power wire were connected wrong, connected opposite. And in another vehicle, your situation was happening and I couldn't find what was causing this, and I finally found what was causing this, whoever installed the previous radio, connected the accessory and power wire together because the radio fuse in the fuse box was blown. A stupid novice installer caused all this.

just the natural parasitic draw of the vehicle can cause the battery not to start the vehicle if the time scale is in weeks. if its still the original battery its probably time for a new one, especially if you have deep cycled it a few times. if you have a dmm you could do a draw check on it and see how bad it actually is.

deck is wired wrong for starters, redo your ground to bare metal not paint/plastic
