    Can you test your alternator with an ohm's to see how much it's putting out while running on the vehical?

    you can test it with an amp meter or a quick check with a volt meter. If you are showing more than 12.4 volts, it's working. But an amp meter will tell you if it's charging to full capability. You can test the diodes with a ohm meter, but it must be a digital style.

    No, you will ruin an ohm meter if you power to it. Unless it is one of the high end ones like a Fluke 87 that should prevent you from destroying it. It still won't read ohms, but you won't need to buy an new meter.
    Like ba said you need to use a volt meter or an ameter.

    Moat parts stores will test them for free. If the truck is running they can proably test it on the truck.
