Ditto most other electronic ignition conversions.  The only exception that I know of is the more recent Crane XR700 (with the LED on the box), which can just be rewired for negative.

Also if you happen to have an early original coil, the terminals may be marked "CB" and "SW" instead of "+" and "-".  "CB" is positive.

A slightly easier method of polarizing the generator is to just disconnect the wire from the 'F' terminal on the control box (battery installed, ignition off) and brush the disconnected wire against the 'A' terminal.  You'll get some small sparks, but nothing major.  Then reconnect the wire to the 'F' terminal and go on.

But the procedure in the VTR article will work fine.
