Hi Rich- Thanks for the info, and now I am really confused. I have thought about putting in external regulation, but have done nothing about it yet so the Motorola is internally regulated as far as I know. I was told you had to rewire the alternator to use an external regulator. What is really bugging me is that I am quite sure that those wires were not connected to my alternator when I took it off last fall. The two bolts in question are tightly fastened to the body, where the two I know I took off I left loose. I also have a picture of the back of the alternator before I took it off and only two wires are connected. But I know the alternator was charging because I checked it with my VOM while the engine was running to make sure and it was putting out ~14.5 volts at the battery. Any way that is possible? Dave
