    On the way to work yesterday the alt took a crap. At first I was pissed but thought better now than 1am enroute to plow. That would have put a damper on things.
    Anyway, not sure which alt I have but am looking for suggestions on an upgrade/source. Its a '94 k-1500 blazer. Thanks in advance.

    When you buy an alt just remember the higher amp you go with the faster it will burn up. 105 to 150 is about lower and upper. Run dual batteries and these sizes should cover you.

    I think the important thing is to read the specs and find out when it kicks on. Plowing at low speeds, a lot times isnt enough engine rpms to turn on most newer alternators. I just replaced mine, it starts working at 1100 rpms.

    You Can Also Changed When The Alt Kicks On By Changing The Pulley Size.

    So the smaller the pulley, the more amps at idle?

    Yes, I have one on my truck and it does help, in fact I'm switching out my alt today for a large case alt, with a bit more amps

    I never knew that-thanks. Was looking at the 200 amp but guess I'll stick to the 140.

    You could also go to an automotive electric shop and have them build one on your core or a replacement, that is amped up a bit. I've gone that route a couple times. I also get adjustable voltage regulators from them, as opposed to the stock ones (Dodge) which don't seem to last very long. Knowing I plow with it I think they bump up the voltage a fraction.

    Thought of the same thing of going to a local rebuilder. I'm a little reluctant about that thinking brand new maybe better. Last thing we need is a voltage problem in the middle of the night.

    Sinc you are on long island you should go sailon auto electric in syosset.
    They are very reputable when it comes to starters and alternators, that's basically all they do. They have created an alternator for ambulances and police cars that creates close to peak output at very low RPMs.
    this would probably be a great alt for a plow truck and i was thinking about getting one myself.

    Sailon Auto Electric, Inc.

    that link is a bit old since that alternator is for sale now, i am pretty sure.
