[QUOTE=bmw325is94]yeah but i am measing resistance in the circut....if there is 0 ohms that means that the circuit is complete. meaning that the positive wire is grounded somewhere. at least thats what i am asuming...somebody correct me if im wrong...so im guessing the problem is a short. although i am still totally lost[/QUOTE
You're going to get a 0 reading because the pos & neg don't connect directly to one another. One side connects to an armature in the alternator and the other to magnets that wrap around it but don't touch the armature. If they made contact that would be a dead short - similar to putting a wrench across your battery posts. When the armature spins inside the magnets it creates a field that creates voltage.
