dead battery?

Question

I put a DUAL AUDIO cd- mp3 unit in recently.My problem is,when first put in it worked fine.Now the battery goes dead over night.HELP?

Answer 1

the battery shouldt die unless something is on over night.that happened to me when i had a pen stuck in my glove compartment.unless the cd player is wired wrong and still can come on when you turn off the car.if that happens then you have your main hot wire on a constant and you need to fix that but you can get your battery tested at any walmart with a tire,lube express or autozone if thats what you think the problem is.

Answer 2

It could be that when the radio was put in, a cable wasnt completely covered correctly and now is touching metal or other cable (very dangerous) causing the battery to drain overnight.

Answer 3

You put the radio in? The battery was fine before? I think I found your problem...
Double check all your connections -including on the battery. Batteries are often replaced merely b/c the connections weren't tight and the battery is thought to be 'weak'.
Or, take it to your local audio shop or have a friend (one whose done this before) and have them check it out for you.

Good Luck!

Answer 4

if yous cd player has a detachable face just take it off when you leave the car then the unit is not using any power and it also helps against theft

Answer 5

the radio is staying on check the red and yellow wires you connect them wrong or use the ilumination wire
