Hey guys,
My car has a problem where if i leave it sitting for a day or more it doesnt start. I know there is a short in the car draining power from the battery when its off. I know someone before me who owned the car put in speakers in the back and took them out but the cables are still there but not attached to the battery.

the mechanic said its not the leftover cable and used the fuse box and everywhere and will keep looking next week.

He said he spoke to a infinti nissan tech who said this is a common problem with this model is this true?
