I have. burned out headlight; if I let my crossfire sit in garage without starting the battery will be dead, could a burned out headlight be the cause? I am currently attempting to replace light; electrical plug is being stubborn

 

No. Way I use to find is to put a trouble light (incandescent, not LED) in series with the battery after allowing it to sit for long enough to turn everything off. Should not glow. If it does then start pulling fuses and relays until it goes out. That is the circuit to check.
