If you are not willing or able to dig in to this with meter in hand, you probably should take it to a competent mechanic. But replacing 3 alternators in the same car is a waste of time and money. If you do not have a multi-meter or know how use one, this is the time to learn.

I've replaced the alternator 3 times and it still won't hold a charge. Won't run without jumper cables or only on a fully charged battery. I've started checking the grounds but after chasing the terminal I only found two! The one on the tranny and the one to the starter. I might just be ignorant but I'm still learning simple things. I was wondering if anyone's got any tips? -Dom
Thank you guys for all of your help! Took whitespider’s advice and invested in a multimeter. It did end up being the fuse shown by blkacc1997. Again thank you all, I am fairly new to this and love how much this car has taught me. I learned a lot from this fuse!
