Dual Optima question

When running two yellow tops in parallel should I put the positive from the engine on one battery and the negative on the other or put them both on the same battery.



If the truck makes it - the trail wasn't tough enough.

Technically is doesn't matter. In reality I would hook up both - and + to the same battery and run a second set of cables to the other Optima. By placing one lead on each battery you are adding an extra thing to go wrong and disable your vehicle.
