    Hey

    I did not turn off the master switch of my battery in the 550 and 6 weeks later the car does not respond when i turn the key... The battery was replaced in the summer (I just bought this car).

    I have a NOCO boost GB40 to jump start it, and I want to make sure I get it right, that is assuming only 6 weeks of inactivity won't have completely killed the battery...
    First, stupid question. The battery is under the hood, at the left top corner (looking at the hood from the front of the car) near the windshield yes? See image attached.
    Second, is there a ground pin for the black cable? I know some cars have something specific.

    Thank you!

    Do NOT jump start it. You may FUBAR the electronics. Disconnect the battery and charge it.

    Not sure what you mean by pin. The main ground cable runs from the battery negative terminal to the battery disconnect switch/knob and the switch is attached to ground. There may be other smaller wires which bypass this on some Ferraris. Because of this not all electrics will be shut off with the battery disconnect switch.

    Most batteries don't like being run completely flat. I would just buy a new one.

    Read some of the negative reviews on the NOCO. Several people claim it will not start a car with a totally dead battery.
