I measured the 10uF cap with my multimeter and it started at the correct voltage, but before long it went down to zero. How does this work if the capacitor goes to zero and the PIC gets no power? Thank you for the help.

    Hi Mike,
    Put the diode in series with the power to the PIC, The capacitor hooks to the Power pin and to ground, on the diodes cathode side. The diode prevents the capacitor from discharging back into the motors, you may need a larger capacitor than 10uF. The only danger I see is if the capacitor is too large PIC might not boot due to too slow of power up. If this still fails, think good thoughts about using rechargable batteries instead of the Cap.
