    while i was down in baja we had pretty gnarly pull out of some deep clay and the winch actually hit the PW kill switch on my engine battery. Given that, i'm going to install a dual battery and bigger alternator.

    I have the 2012 PW but i guess the original owner did not op for the larger alternator.

    any recommendations on setup?

    After talking to the dealership, it doesnt seem a dual alternator was an option for 2012 and they did not seem enthusiastic about attempting to upgrade it

    I tried to get the 220 Alt but I added it as an afterthought and it's the only thing I didn't get so I'm stuck with the 180 for now.

    I assume you can just swap them out if you want to...

    And just a thought, your alternator is 5 years old, maybe it's not up to 100%? Or maybe your battery is going? You might not need to upgrade, just replace back to 100%... (wishful thinking. :) )

    so i could upgrade at least to the 220 at the dealership? the battery is only a year old so i think its good.

    I have seen videos of people revving their engines in older power wagons while winching. I guess this is why. I did order mine with a 220 amp alternator just to be safe.

    dealership said you cant just swap in a larger alternator so you need to find an aftermarket kit of some sort

    Not sure I believe them. I would go to Autozone and take a look at both and see if they are the same size. Bet the 220 is the same size with just more wire windings inside or some such thing. I'd be really surprised if the 220 made that much of a difference. But thats just a guess, I could be wrong. :)

    I have factory dual alts... i would look into that... you'll need a lot more juice for those winches than 40amps extra after factoring in loss of efficiency
