well its nice candy apple red, 5spd, ahh nice. well i went to start the car and the car goes click. well first thing that popped in my mind was like oh no the battery. so i turned on some accessories and no that didnt work. so my friends dad got the voltmeter and the battery said nearly 13 volts. well he told me to try and start it and i did and the battery went straight to zero. so the battery completely shot? well we started it with the jumper and sometimes the gauges would flicker and the battery light and abs light will flicker on and off. so is that contributed to the bad battery? i gotta ask these questions cause i just spent $11000 on it.

Did you clean the battery terminals and connectors, and check the water level in the cells? Both a bad battery (high internal impedance) and bad connections could cause those symptoms.

dude those battery terminals are clean as heck and are on purty tight. dont know about the battery water level.

battery is dead, of course it will go to zero under load. Bad batteries will still register a voltage, even 13, it just can't hold it. it could also be the alternator not charging it. jump start the car and once it runs, disconnect the neg batt cable, if the car still runs, it's the battery's fault. If it shuts off you need a new alternator.
