How to charge a Flat Battery on the XJ with no access to the boot!


Recommended Posts

Credit to Paul Bennet on Facebook for the following Tip!

If you have a modern Jag and the battery goes flat, chances are the key to the boot will fail - preventing charging. There is an electronic deadlock on the boot lid. Solution - (on the X308 XJ) under the bonnet follow the main lead from the battery to the auxillary fuse boxes on t...he front right wing (as you look at the car). Two securing nuts for the cable are covered by rubber boots. Attach the positive lead from a charger to the nut and the negative to the car body. Plug in and charge - when sufficient power is there use the key fob to release the boot - this should allow the boot lid to release. Much better than main dealer solution of 'drilling' the rear plinth.

Would still be a lot easier if you could use the emergency key to open the boot though. But this is nitpicking . Had a young lady knock on the door yesterday asking if I could possibly drive her to church to get married , she thinks the XJ Superport is fantastic !
