Voltage Regulator Failure

I found out the expensive way that the instructions in the sticky on the Electrical/Lighting/alarm forum are not correct.
The sticky says if there is continuity from the DC output of the regulator to the AC input of the regulator, the regulator is bad. The new regulators don't check like that.
I followed those instructions when I was having a charging issue. I went through two regulators that according to the sticky, where bad. Before installing the third regulator I did a complete inspection of all the wires on the bike. I found the DC line from the regulator to the battery had rubbed against the frame to the bare wire. The wire is zip tied to the bottom right side frame member and hard to inspect unless ya cut the zip tie.
I mentioned this to my local indy and he went and checked several Harleys in his shop and found the regulators all had continuity from output to input.
Now, before ya go off and start asking if I had the ignition on or was the bike running, think about this. The only way to check for continuity from the regulator output to the regulator input is to have ALL wires disconnected. As if it were sitting on the bench, 20 feet away from the bike.

Glad I found this thread. I was having some electrical issues(stranded).
Did all the tests and found I was getting AC from the engine, but the battery voltage didn't increase while running or when revving.
Not sure what the problem could be at this point. I have AC power and replaced my regulator with a cycle electric model. I am going to double check my connections tomorrow. Hopefully that's it.
Possible I got a defective part??

14.7 is considered the highest. Is your meter good enough? Does that make a difference?
I dunno. If you have a light bulb blow, then I would probably change it out, but if not wait and see. I'd be little concerned, but it is close, and regs cost money.
Be nice if you could check your meter on another bike, to see if it reads the same. I am using a $250 fluke meter to read .10s
