       This is the start to what will be a very long discussion topic..
       All Automobiles use electrical systems, and with today's
       technology these systems are becoming more and more complex. How
       vehicle computer systems communicate, how circuits operate
       All of these systems start with the heart of it all. The
       battery. The battery is a 12 Volt source composed by layering
       Peroxide and Lead Peroxide plates together. Peroxide plates
       making the positive cells, and Lead Peroxide creating the
       Negative connection, then filled with an Electrolyte
       liquid/Distilled water. Whenever beginning with any system
       understanding or diagnosis, it is very important to verify the
       systems charge as this will greatly affect how the circuit will
       operate. The battery can be very dangerous if improperly
       connected to or serviced, however most batteries today are not
       serviceable. Whenever a charger or power source is connected
       across the battery it is critical to verify fluid level within
       the battery. Fluid within the battery is one piece of the puzzle
       separating the cells within, if fluid level is below the top of
       the plates a short circuit can occur causing an explosion or
       fire. This creates an obvious hazard to be injured. An
       automotive battery is capable of producing high levels of
       amperage.... to be continued
