Door Opener

The Boxster Technical Bulletin shown below describes how to open the front trunk when the battery is discharged or disconnected:

[I deleted the scan for copyright reasons. It wasn't readable anyway.]

Since this is not the world's greatest scan, the following is the summary of what it says:

Front and Rear Hood Release Inoperative [grp5 1/96 5510 1/21/97] 1pg

Should the front and rear hood releases become inoperative due to a disconnected or discharged battery, the following procedure will allow the hoods to be operated electrically under these conditions.

• Open the left door.
• Using an external battery, connect the negative lead to the door stop.
• Connect the positive lead to both sides of fuse "C3" (see illustration below).
• With the door open, move the door latch with a screwdriver into the closed position.
• Using the key, lock and unlock the door.
• The front and rear hood releases can now be operated.

Note: If the vehicle is in the workshop and the battery must be disconnected, try to park the vehicle in a safe area where it is not necessary to latch the front hood.

The diagram shows the same stuff as the bulleted directions above except it shows putting a 30 amp fuse between the external battery positive terminal and the C3 fuse.

My Solution

I constructed the device below to match the diagram given in the Technical Bulletin. There is a battery terminal connected to 16 gauge wire to a 30 amp fuse holder, that, of course, holds a 30 amp fuse. This is connected to two fuse blades that are put over a 15 amp fuse and whole wrapped in electrical tape. I have not tested this, but in theory it should work. The idea is to connect a set of jumper cables to the door stop and the battery terminal on the constructed cable, then plug it into the C3 fuse and follow the directions given above.
