Okay I'm driving a 1998 Honda Civic EX and I have an audio system in my car that is about 7-8 years old now.
I had done some work on one of the terminals on the subwoofers, and melted plastic in between the terminals as an insulator. After about a month, my CD player started flickering on and off again, as it does nearly every winter, which also happens during heavy humidity or rain, because there are some air leaks in my car as I have wrecked it a few times.
So far I have replaced the alternator belt, the battery, and the headlight switch. We fixed the headlights a while back, and I ended up hitting these pot holes strewn across I-40 around Knoxville, TN, jarring something once again.
I'm certain that the battery drain is directly connected to moisture but even after unplugging my main fuse for my subs coming from the battery, and disconnecting the faceplate (which works on dry days/nights at work). My problem is that my car battery dies while it is turned off for 8+ hours but not while it is running.
Once the power is disconnected, power shouldn't be able to drain, unless there is something physically broken and touching in the cd player, however, without the ignition on, there shouldn't be any currents at all. I have a ticket from the city I live in and a city I recently visited and I'm supposed to have it repaired in about 9 days. What could be causing the issue?
Also if I disconnect the battery for about 30 seconds, the cd player will forget that it was messed up, and turn on again, until I turn the volume up to high, at which point it will flicker to the point of just shutting off.
Note: The head lights are not related.
