I don't doubt that.

But tell me, on any of those vehicles you worked on, did you measure the voltage output of the alternator while the fuse was blown?

If you did, you would have found the alternator putting out it's rated voltage while running.

It'd be like a battery that isn't connected to anything. There is 12 volts sitting in that battery on the bench, but nothing is connected so the 12 volts doesn't go anywhere.

when check running or not being that it is in line the reading will be 0, if the fuse is blown it will show an difference (running 14.1, off 12.6 estimated). If the fuse isn't broken it will read 0 as its an complete circuit and if not then its an open circuit.

Right!

We're saying the same things, just in different ways. The 14.1v you read when the engine is running and the fuse is blown is what I am talking about.
