I used a 12 volt source and connected the negative to the door hinge, the postivie connects to a battery connector that pulls out in the fuse box.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

23 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

0 evidence records excluded for query context · 0 excluded by outcome qualification · 0 adjusted by outcome qualification.

2 acknowledgements have no verified action link; they do not establish a repair result.

POST 1 / ORIGINAL POSTEROriginal post

I can"t open the trunk to get at the battery.I hooked a battery to the jumper post at the fuse box as directed by Porsche but the trunk will not release .Any ideas?? Surf 02 996tt

POST 2Original post

keep trying. it happened to me in my 4s and i had to find the 'perfect spot' in order to transmit current. it will work, it just might take some time fooling around with the location. good luck.

POST 3Original post

Make sure the power is in the car. Is the lights on? Then the power is going to the trunk too.

POST 4Original post

Just in case the above method does not work for you. Battery maintanier is another opition.

POST 5 / ORIGINAL POSTEROriginal post

Ihave looked for the sweet spot on the contacts to no result there is no power going to the car..The battery in the car is completely dead.Can you trikle charge the battery from the fuse box contacts.?Is there an emergency trunk pull behind the head light?Help!! Thanks Surf ?

POST 6Original post

Page 214 of the Owners' Manual details the procedure to open the hood with a dead battery.

POST 7 / ORIGINAL POSTEROriginal post

I tried the procedure .No luck. Surf

POST 8Original post

I don't have a manual handy, but I have done this before. I used a 12 volt source and connected the negative to the door hinge, the postivie connects to a battery connector that pulls out in the fuse box. Once you do that, if the source is charged, you will have enough power to open the hood... Roy ps. I actually use one of these, not a battery: http://www.enjoythedrive.com/content/?id=10023

POST 9 / ORIGINAL POSTEROriginal post

I did that but it did not work.It has worked before but not now?????????? Surf

POST 10Original post

I own a Porsche trickle charger. Plugs into the cig. lighter and charges the battery. It has worked for me in this situation before. Might be time to change the battery?

POST 11Original post

Make sure you're getting a good ground. Where are you attaching the negative lead to? Alternatively, you can go through the cigarette lighter too.

POST 12Original post

POST 14Original post

You sure the battery is not so flat that it's a short circuit?

POST 15 / ORIGINAL POSTEROriginal post

I think the battery is dead flat.If so how do you open the trunk? Thanks, Surf

POST 16Original post

There is an emergency cable release hidden behind the passenger side headlight (you might have seen it if you've ever had your headlight assembly out). Its a very thin braided steel cable. If you look in between your headlight and the body, as far towards the center of the car as you can you might be able to see the cable and fish it out to release the trunk latch. You'll have to look in there with a flashlight, its a PITA.

POST 17Original post

Aha, this happened to me. You can jump it on the engine. There is a positive post there and you can get the car enough power to release the trunk. Porsche Roadside assist didn't even know about it.

POST 18Original post

The engine compartment is also electronically controlled so you cant get to it with a dead battery. I was told the cable on the newer 996s is on the drivers side behind the fender skirts. The dealer said it will take over an hour to disasemble and find the cable and replace. Best thing is to charge the battery via the cigarette lighter.

POST 19Original post

Happened to me about a year ago. Nobody had a clue what to do. Had to flatbed the car to the dealer until they figured out what to do. I tried to jump through the engine too but it didn't work. You might want to try and trickle charge the battery through those posts in the engine. Im not sure if a trickle charger will work but am not sure. After I got the car back, i removed the headlight and moved the emergency trunk release cable so i could access it from the side marker light. Bobby

POST 20Original post

I have seen the emergency release cable procedure detailed with some pictures here: http://www.renntech.org/forums/index.php?showtopic=2151 Do a search for more threads if necessary. It seemed ill-designed but you don't have many options.

POST 21Original post

I keep in my passenger side pocket a cigaret lighter to cigaret lighter device to connect to another car in the case that happens. Cambell Hausfield makes a combination Air Compressor / Power Supply that includes a connector to go into the cars cigaret lighter socket. I use this when disconnecting my battery, to keep from lossing the radio codes and settings. This will also give you power to pop the hood.

POST 22Original post

I sent you a PM with the instructions, but ask that you don't post them--we don't want our trunks broken in to!

POST 23Original post

The same thing happened to me and I was able to open the trunk with the key fob but not with the switch on the door jam. Good luck.
