This is a photo of Mod II of the burn test kit. I used a household-type, surface
mounted switch (at 24 volts, about 100 amps rated), and the wire is a 12 gauge
stranded... the connector is a Radio Shack part # 274-151 (male) and
#274-154 (female)... of course, the motor and battery sides of the scooter wire
had to also be converted, as did the charger, but it's worth it! Resistance
at the connnector (switch "on", of course) is about 1.8 ohms.

The next image is of Mod I... the connector and switch
were much too flimsy... this rig really needs to be over-engineered.

The photo below shows my laptop hooked up to a digital volt meter, which is reading the
voltage from the battery as it is being discharged into the test rig. I'm taking a snapshot every second
and will produce a graph. As I have time, I'll write my own software that will create
the graph on the fly as well as comparisons with previous tests.
