Thanks for the info. That's the test I did and it showed 7.3 amps. I have someone who is going to come check it this weekend. The electrical diagnostic manual is the one I don't own, but he has one so we'll see. I think it's the voltage regulator based on what I've done so far.
As for voltage regulators, the only check for them is when you are producing voltage (as I see it in the manual). I have no idea what is being passed through or what is connected to the VR when the ignition is off. I guess you would have to look at the wiring diagram. I did note that it said to disconnect the VR from the stator wire... as far as I can tell the only thing that the VR is hooked up to is ground, the stator, and the battery ground. So... if you disconnect it from the Stator, then you won't have any thing that could provide any amps to anything involved. The VR doesn't hold voltage and if it isn't connected to the Stator, there is nothing else that it can get power from. The stator isn't connected to anything, either. That would mean that you have something hot hooked up to ground somewhere... and it is being passed through the ground any place you hook up to it... and the VR is just innocently passing that through to your multimeter through the ground.

@cwsharp: I probably didn't explain what I did very well. I unhooked the negative battery cable from the battery and then put the multimeter between them. When I do this I get 7.3 amps, but if I remove the voltage regulator wire from the circuit breaker, it goes to zero.
Hopefully I can get this figured out this weekend, I have a friend who is a certified HD mechanic coming over to check it out. If it's a wire grounding out somewhere it will probably be a nightmare to find it. But knowing what circuit it's going through might help.
I did unplug the voltage regulator and checked the resistance in the stator by putting the multimeter across the terminals which gave me 0.6 ohms.

I'd advise against having a car running while jumping it, car battery's systems usually have a lot more amps, and you don't want to fry anything

The battery has been replaced so that is not an issue.

It's fixed!! After all the guess work and various checking of parts and fuses, we finally found the problem. One of the wires in the fuse block that runs from the battery fuse to the TSM was corroded and finally broke off while we were checking everything. The only way we were able to find it was to remove the fuse block from the bracket and turn it over to see the underside. As we turned it over the broken wire was exposed and the end of it was green with corrosion. We took one of the terminal ends from the spare fuse area, soldered it in, covered that with shrink tubing and put it all back together. As soon as the battery was connected the speedo. came back on, the turn signals worked and she fired right up using the switch. We ran the diagnostics and everything is fine now.
I appreciate all the help and direction during this and I'm glad it's fixed. Hopefully this will help someone in the future who might have something like this happen to them.
