What happens if you overload the alternator? My Dad's 120 diesel Prado has a 40A DC-DC charger under the bonnet for his 2nd/3rd batteries. He's just added an anderson socket at the back of the car (from the main battery) to connect a camper trailer with a 30A DC-DC charger in it.
From searching PradoPoint it seems the factory alternator is 80A - if both the DC-DC chargers were going flat out that would be 70A. I'm guessing that charging the starter battery pls running the car, A/C, lights, etc would be more than 10A.
Does he need a bigger alternator? Or does it gracefully cope with being overloaded? He's keen for it to not die in the middle of nowhere (next trip will be Tassie over Christmas - not the best time to get something fixed in a hurry!)
I saw that 130A alternators are available - do they need upgraded wiring and fuses or can you just slot one in?
