Outer Limits 4x4 Board

i have a ex telstra 2005 i have a power prob it seems to like using alot of power and draining both batterys over the weekend not being used i have changed old batterys with new ones and its still doing it if anyone has any ideas what it could be i would be greatfull thanks

I had the same problem with my old TB45. It ended up being the alternator. Faulty diodes that caused a current drain .
Worth disconnecting all wires From the alternator and using a multimeter to check current.
