my freinds and i recently did battery relocations on our cars and we are all having the same problem...

with the car off/key out- for example we press the button for the air to point down to the ground it will light up. if we turn on the air it wont turn on but standing from the engine bay you can hear it going for some reason??

 

?

 

what button for air lol

 

slide button

 

bump for help

 

How about some more info? How did you relocate? Where are your battery cables going? Does the radio come on with the key off and out of the ignition switch?
