Default How many wires into alternator?

OK, so on Dec 28th I replaced the alternator because anytime it would rev above 2500 the volts would drop down to 9. This fixed the issue, however, last night it dropped down to 9 and stayed there for 1/2 hour drive home. Of course, after a while the battery light came on. When I first start it, it runs at just a hair above 14 volts, but after 5 minutes of idleing or starting to drive it drops back down to 9 and doesn't return. I took the alternator and battery in and they tested good.

Now, when putting in the new one I noticed there are two wires on the positive post of the alternator. I would think that there should only be one that goes to the battery, correct? Also, the plugin for the voltage regulator only has 1 wire in it. Is that correct?

Thanks, otherwise any other ideas what could be cause this?

I have to look at my battery. But I think one wire goes to the alternator the other goes to the fuse box that has the DRL relay and ect.

Here are the starting and charging diagrams for your year. There are two fusible links, one that runs between the battery and the alternator and another that runs from the alternator to the starter relay.



I am not sure if all of these each have a different terminal at the alternator or not.
