I just got my 2007 Bentley Continental GT and everywhere I have read, both online and the manual, say the 12 V adapter in the boot is always live. It seems like mine is the only one that isn’t so I cannot use a battery tender to charge both batteries at once. Is there a way to fix this? Thank you. I have searched the threads and found nothing.

 

Hi Wyo.

It could be a blown fuse. The fuse info is in the service book normally.

 

Hello ExSF. I apologize for my omission. When the car is running or has power it has power like all the other lighters.

 

Ah! That has stumped me, sorry. There should be another socket with a special adapter for charging. It isn't like the Cigar lighter sockets. It's normally on the left half way up the carpet, ahead of the battery cover as you look into the boot.

 

Nothing found in the boot unless there is something in the spare tire location. I looked in the area where the spare tire is and there are two connects and I am wondering what they are for or where to find out what they are for. Any ideas would be very helpful!

 

Greetings, I also spent time finding that the 12V socket on the left side of the trunk is controlled by the ignition. I enquired at the dealer, and they quoted $395 to install the Bentley retrofit connection so got to thinking of alternatives. In the end I removed the battery cover, pushed the 12V outlet out from behind (it's held into the board with spring tabs which are easily pushed in) thus exposing the wires. I clipped the wires, leaving about two inches on the socket, and insulated the remainder with tape as it will be live when the ignition's on. With this done, I crimped extra wires on the socket and ran them through the socket hole in the trunk wall to the battery terminals. The socket then fitted back where it came from and is now live all the time, and ready to take the cigar lighter connection from the CTEK device. Upon switching on, the CTEK worked fine, and indicated that the battery was a tad low. After a couple of hours the indicator showed a better result so I'm rather pleased with the investment of an hours tinkering and some spare wire. I hope this is a good fix, but if anyone sees something I've missed, please let me know.

 

Sounds fine, just make sure you DO HAVE the fuse still on the CTEK female (battery side) wire. In other words, short adapter wires attached to battery/chassis/whereever, then that wire has a fuse, which then has on the opposite end of the battery connection end of the FEMALE CTEK connection.


Just the short wire bit

This short wire assembly has female end connection.

 

Many thanks Steven, sound advice indeed.

 

Thank you Time2Go and Steven. I never really thought about wiring differently, thinking of keeping everything original. I did look into it and saw that you could tap into the fuze box and make it look very clean. Just shows how long it has been since I have done car wiring. I like the idea!! On another note if anyone needs some information on replacing the boot motor I found out mine was not set in the plate correctly. It was at an angle which wore off the first 3mm or so of the gear. With it set correctly it fits on the male gear like it should. I may not have need to buy a used motor.....

 

So that I'm understanding this right, the lighter looking plug on the left in the trunk/boot is not wired so that a charger could just be plugged in and ready to go? I just bought the CTEK 7002 with the lighter adaptor. And I'm still going to have to modify some stuff?

 

 

Oh ok. After getting a few mins, I finally connected my tender and it's working as it should. With the cig adapter, I like how it flash red, yellow or green. I think I need new batteries because mines always flash red when I first hook it up. I was pricing some Odessey batteries from some online company. Really want to get the best for these cars.

 

 

Just checked my 2009 GT and the trunk plug IS live. Are both batteries topped off with a battery tender plugged in?

 

On the fuse taps I've used, you don't need to match amperages as the tap itself seats into the original slot, feeds 12v to the second fuse and pigtail yet keeps the pass through amps on the original fuse for that circuit. Just make sure you have the original amp fuse in the correct slot in the tap. Might be nice to try and find a matching amperage with ign on all the time, but not likely you'll get that lucky. Most circuits will be switched.
