A freestanding portable holding apparatus for a handheld mirror comprises a base which ensures stability and a center-mounted pole extending upward from the base having a height adjustment mechanism that allows the pole to be extended upwards or downwards as desired by the user. The system comprises a roof frame and a cover. Through the use of impedance and inductance, the present invention can either produce a low voltage replica of the waveform of the high voltage electrical signal which is directed to a spark plug or can effectively prohibit that spark plug from firing by short circuiting the low voltage side of the transformer of the device. An electrolytic capacitor comprising an electrolytic solution, at least one anode foil, at least one cathode foil, and separator paper between the at least one anode foil and at least one cathode foil, wherein the separator paper comprises paper impregnated with a soluble silicate.
