Ahoy Skip,

I have two KISS wind generators aboard and so I read with special interest
the description of your experiences with your unit.

Since you mentioned you had the unit apart to check the bearings I know you
are familiar with the insides of the machine.

You mentioned "special circuitry" to prevent overheating in high winds. 
The "special circuitry" consists of simple thermal switchs (they look like
giant transistors) on two of the three phases of the alternator.  These
switches are connected using 1/4" quick-connects, then covered with copious
amounts of shrink wrap making a heavy, unsecured lump supported only by the
wires connected to them, which includes the solid copper wires of the
stator windings.  When the normal vibration of operation is applied to this
heavy gob of matter it is inevitable that the stator wires break, which
happened to me several years ago. 

I discovered the problem after noting low to no output to the batteries. 
When I checked the actual three-phase ac output of the units I discovered
no output on the phases with the broken wires.

My cure was to remove all the shrink tubing and the quick-connects and
solder the appropriate wires directly to the quick-connect tabs on the heat
switches.  I put a piece of normal (the original was a very heavy wall
material) shrink tubing on the thermoswitch then lashed it to the stator
with fishing line.  

Thanks for the heads-up on the switch problem.  Those switches are just
about useless anyway.  Even with them on the units can be spun up by strong
winds.  I may remove them like you did.

I use a light line with a loop from the tail with the loop around the mast
to secure the units.  I stop the blades by turning the unit away from the
wind with the line to the tail, then slip the loop up and catch a blade tip
with it so the loop is around both the mast and the blade tip.  This is
secure in all conditions. 

The KISS units look good and have good output (when they are working) but
they are poorly made and have several designed-in defects.  I would not buy
them again but I would search for better units.
