You have a draw on the battery. Short circuit somewhere in the electrical. Must use OHM meter and start checking wires, Start near the alternator and ignitoin work away from there. A quick look over all your wires to see if there are any noticable cuts or frays may save you some time if your lucky. Jags are known for electrical problems.
U can't charge the AC at home on this model, there is no low side charging port, the system is charged through the high side port which requires special equipment to do this service, any automotive AC shop can do this recharge service, i assume your system has been retro-fitted to the new R134 Refrigerant, if not that will need to be done as well.
you'll have to check the alternator to be sure .Because if it is not charging it means that the current goes in. But it does not go around the alternator . It means that there is a wire from the coil that is not connected .You should disconnect the alternator to your car for inspection.
check your suppression module. driver side front close to alternator. It control how the battery charges the alternator. If you battery goes dead, after charging lock doors until alarm activates and you are now ready to star your car. email@example.com
