Probably the only thing that will make a difference there Norm is the heavy wire, which I would run everywhere, not just to the motor control. At least 10mm wire, something like ride on mower starter cable. Without knowing the exact alternator, it could well be a self exciting variety that doesn't need the extra wire other than to light the Alt light on the dashboard. Believe me, there is no difference in where the wires connect in this machine, current will flow where it is needed, just think of electric current the same as water in a pipe.
