I installed an HID conversion kit 2nite. and when i went to turn on the car the battery was dead. i figured "well i had it on all night playing with it and turning them on and off and playing with my system it probably killed my battery". so i went to jump the battery... long story short im a f*kin idiot and flame me all u wish because i deserve it, i fried the cables and almost caused a fire in my driveway. anyway on to the questions, is my battery still useful? could this have fried my ecu even tho the car never got turned on? could this have shorted my amp in anyway? is there any other damage i should be concerned about? Thx for any and all info.
