I notice after hooking up the fusion brain to the car power system that the blue l.e.d light stays on. Does this draw power from my battery when the car is off? I use a dry cell battery for my system. which I leave my computer in standby overnight for short boot up times. my car starts without any problem the next day. I dont want the fusion brain to drain the battery dead. It a 62 amp hr kinetik car audio battery.
