electrical, my van has a broken wire to the alternator terminal.

Before you touch anything under the hood.... disconnect the battery negative cable and lay it aside!!!!!.... Without more useful info, can't help much!... Maybe you can use a solider-less (crimp style) wire terminal, avail at parts store in different sizes, to repair the connection... Check out YouTube for a how to video on this subject!... Got to know a car savvy person around the neighborhood!!.. Good ol southern hospitality!
