    very slim chance a second battery will keep the lights from dimming. Second batterys will only give you more reserve

    I upgraded the size of all the ground wire and positive running from the alt to the battery. I used 0 gauge car audio cable. Cleaned up all the contact points and it helped a lot. I than got a high output alt and there is almost no drop in voltage. Google "the big three" it can explain a lot better than me

    Alt....Alt power wire.....ground the alt with the same wire as the output wire

    Do a YouTube Search on it - much easier to watch it. New thicker wiring on Positive Terminal - Negative Terminal and Alternator/Ground...etc

    raise your plow while in neutral, makes a difference

    nope...less drain on idle so alt performs better....unless you are in a hurry and like fixing stuff....goes back to the days of using a clutch, if your old enough

    eh you do have a point but I dont think it would make much difference.. I do drive stick but never plowed with one.

    Altos don't perform good at idle period..I think alts perform good from 1200 rpms up depends on the alt biggest thing is what they put out at idle usually isn't enough that's why the voltage drop

    Plus the wiring isn't big enough
