Took the GTX out last weekend without any issues and went to head out this morning but had a dead battery. I have never had that hapen before, so I threw the battery on the charger. As soon as I connect both wires to the battery, you get the familiar beeps and the dash lights up and says "KEY". I put the key on and started up fine. I took the key off and the dash stays on along with the beeping like the key is still on. Fairly stumped as to even where to begin, any help is greatly appreciated.
