Hello folk. Just moved to auz and bought a 2004 prado 3l diesel.
it came with a dual battery installed and a mean mother distribution board in the back and a redarc solar controller.
got a 50l brass monkey dual zone. Seems to be drawing around 2.4amps according to mm distribution board.
so the question is. The max voltage I was getting when the prado was off was 12.2 at times going down to 11.2. Then the battery died 9.2v (some leaking noticed, second battery in engine bay).
so I got a new battery and wrapped it in insulation, 97 amp.
when the car runs the starting battery gets to 13.8 volts. The second (new) battery fluctuates between 11.6 and 13.2 volts (depending if the fridge is cycling). All I run is the fridge when camping, driving around 5-8 hours a day. Currently with car off and fridge running battery is reading 12.1 volts. Battery is 2 days old and drove 6 hours today.
long story short where should I start problem solving? I am assuming it’s not a smart alternator so is it as simple as a second positive from the alternator to the second battery? The previous owner who paid someone to do the install explained how there’s a push down button which links the two battery’s together.
I can provide any photos or additional information as needed, just need a helping hand to point in the right direction
thanks in advance (from the girlfriend, who says this battery and the voltmeter are going to be the end of our relationship)
