How to Jump a Dead Porsche 918 Spyder Battery
We have one of these in our shop. And unfortunately a door was left cracked and the 12v battery died. We couldn’t gain access to the frunk and there’s not the traditional fuse panel on the drivers side floorboard.
We looked this car over everywhere, we searched the internet EVERYWHERE, and couldn’t find anything.
We called multiple Porsche dealerships, they couldn’t tell us either.
Finally we somehow got an actual 918 tech on the phone and explained the process to us.
So here’s how to do it if you’re ever in this fortunate situation lol.
Passenger side floorboard underneath the glove box is a rectangular fuse cover it’s very hard to see and easy to miss.
Pull this off and there is where the magical red pull out 12v connector is to attach a jump box to and give it enough power to get into the frunk.
BUT*** the tech made very clear to remove the carbon fiber foot mat (1 t30 bolt) because when you jump the pull out connector it can arc to the mat and be very dangerous.
Once you gain access to the frunk on the passenger side there is a cover you take off with flathead screws. Underneath this is the actual positive connection terminal to charge / jump the battery.
I couldn’t believe this was NO WHERE on the internet so i hope this helps someone someday.
There is also a cigarette lighter connection underneath the front of the passenger seat you can use to trickle charge.
