Along with Jim's comment, unless each battery is 4 Volts, you must mean that you've wired them in parallel. e.g. like this:

Was the engine running? Shouldn't the Yandina combine the batteries when the engine is running?

Maybe there's a load at dash that comes on when you supply power to it? (connect aux. batteries)

I would suggest that you check all fuses first. Do you have two aux. battery systems?

Assuming you accidentally connected ("hit") the battery + to the vehicle frame, what happened makes sense; there would've been no fuse between that + post and vehicle frame.
