battery drain
I have a big drain on my battery. When I unhook the top post on my alternator, the fusible link wire from my solenoid, it goes away. Replaced the alternator and also tested my harness, it checked out good. What could be next? I am going to replace my voltage regulator next but I am out of ideas. Any help appreciated.

I unhooked my negative cable on my battery post and put a test light between the neg. post and the cable. When I have everything hooked up, the light comes on in the test light; when I unhook the top post on my alternator the light goes out. Also I don't have power to the wire that goes to the "field" connection on my alternator. Since the alternator receives power from the voltage regulator I was hoping that was my problem. Hope this sounds better than my first post.

I would unhook the regulator and see if the light goes out.
I would also unhook all the wires to the alternator except the output wire, and see if it goes out.
If you have nothing hooked to the alternator, and the light comes on when you put the large wire on it, it's got to be the alternator.

I have already replaced the alternator, there is a capacitor on the voltage regulator if the capacitor won't hold the charge could this be the culprit? I have also disconnected the regulator and the light doesn't go out. It only goes out when I unhook the top post on my alternator.

The capacitor is only there for radio noise. And the one you are talking about is hooked to the regulator correct? And you unplugged it, so it took it out of the circuit. I can't explain it, but if the alternator is causing the light to come on, then it's the culprit. If you unhooked the regulator, then it's out of the picture.
Take the positive cable off the battery. Run a short piece of wire from the alt output post to the battery +. If the light comes on, you have nothing in the circuit but the alternator.
