    In 24V:
    Neg of charger to Neg of 1st battery. Pos of charger to Pos of the 2nd battery. Use jumper lead to connect Pos of 1st battery to Neg of 2nd battery.

    In 12V:
    Connect charger to battery Pos to Pos and Neg to Neg. Use jumper leads to connect other battery Neg to Neg and Pos to Pos of battery getting charged.

    My land cruiser has similar 2 battery set up but runs on 12v. The second battery still has its factory cover with dire warnings against 24v operation/charging etc. .

    Is hers a 24v truck?? If not there’s some smart electrical stuff to manage the 24v start and 12v run. An auto sparky might be a wise place to avoid smoke and tears

    Yip don't charge them 24V in the truck - sorry I should've made that clearer
    They're only a 12V system

    not a good idea to parallel charge batteries, can result in bursting them/overcharging or ignition

    @Vietnam cam, sure theres no differential splitter in the circuit? paralleling batteries on charge can be hazardous if one is "flatter" than the other. especially gel cells. seen a couple of Li ion batteries ignite from parallel charging too

    Not that I have seen....just big cable linking 2 or 3 4wd sized batteries to get enough 12v grunt....dunno why they dont run 24v like most others.

    My Isuzu Bighorn and the Boss's Toyota Hiace are hooked up like this too.
