Jente - I just realized that photo is not complete as the factory alternator is not mounted yet. It goes directly underneath using factory
brackets. The second alternator on top is fixed, and the ac adjustor pulley tensions the belt. I have an isolator solenoid so the dual batteries are
separate. I use the main battery for all factory operations, starting, lights, heater, glow screen, etc. The second battery is a separate hot buss, with
a 750 Amp isolator for both off, front winch on, or rear winch, or both on. I ran 2/0 battery wire to the rear for the rear winch and Anderson booster connection.
The second battery is for winches, driving lights, webasto, powering fridge, and all other 12V bits and pcs. It seems to work for me. I've done it all myself.
My truck is converted to all 12V. Too much hassle running two voltage systems. If you have more questions, ask. J
