I'm building a K2.  The [DISPLAY] button shows a voltage of less than 2
volts and it is erratic and, the current is shown as 0.00.  I have checked
the voltages at U3 and they are 2.633 at pin 5, 6, & 7, and 13.75 at pins 2
& 3.  Pin 1 is .571.  I measured the voltage at Vsense on the MCU pin 5 and
it was 2.669.  Where could I be losing the signal to the lcd??
