[P.S.]

The fuse is never a bad idea. However, if running a fuse and an original sytle generator, you should modify the electrical system just a tad. I would run a wire directly from the generator to the battery with its own fuse, the run the wire from the fuse block to everything else.

If the fuse between the generator and the battery blows, you simply stop charging, and your ammeter would show that. if you blow the fuse between the battery and the car's electrical system, then everything comes to a halt, including the motor. That may sound bad, but a new fuse gets you going again and doesn;t allow the generator to run directly into your electrical system with no battery load.

Best bet of all- Run a separate fuse for individual circuits!

I decided best bet for my car was an alternator and the single fuse for all with a separate fuse for some electrical components. The planned project for this winter is to install a block under the "dash" (fuel tank) with separate fuses for individual things like lights, horn, ignition, etc.
