Figure 3. Charger features and components

A. Output Contact:

 The output contact is connected to 

an internal power source.  When the touch plate located 

underneath the unit is connected to ground, the output 

contact will provide a charge of the indicated polarity.  

The charger is designed so that an operator can press 

the rocker switch and touch the plate simultaneously 

with the fingers of the same hand.
