Hello guys
I have searched for days on end and read so many threads but cannot find an answer to a small question I have which potentially could solve a variety of SL bootlid/PSE/ Consumer battery issues...
My fuel is low and the central locking is stuck in lock position for the fuel flap etc
Is there a terminal or point that runs into the car from the consumer / auxillary aux battery (in the boot) that I can intercept the live wire so that I can charge it?
I have had my fuel flap/glove box/ arm rest/cubbys not opening due to low power on the boot battery and after I took a long drive or charged the front battery via a car charger it worked. Also removal and refitting the 20 amp fuese behind the drivers seat in the cubby also worked
I think if we can identify this wire it would avoid anybody getting locked out of their boot or becoming stuck with fuel flap not opening when you are low on fuel
** Reffering to a thread made by Bikerng , I belive his username was (regarding charging both batteries together), he refers to an unused relay in the front fusebox infront of drivers side which provides power to the rear, can anyone confirm which one exactly?
Thanks in advance for any input
