Ok so I was parked outside my friends car with the engine running and all of sudden noticed that the emergency blinkers all of sudden dimmed and it wasn't even bright in the cluster. Suddenly the car shut off and would start and when i tried all you would hear is clicking. i tried to jumpstart but wouldn't work. I recently finished my h22swap and 5speed swap and had to get the car rolling get it in gear lol. I don't have any subs or excessive audio equipment but where should i go about first? Alternator or battery? and what brand of battery if so? Thanks
