3.  Wiring 

An internal or external battery is connected to the charger by means of the INT 
(Internal) or EXT (External) connectors, as shown in Figure 1.  An “external 
battery” cable is available for the charger.  This cable connects another battery 
with the charger to provide power if the main battery is removed.  The red lead 
connects to the positive battery terminal and the black lead connects to the 
negative terminal. 

Reversal of polarity of external battery will damage the 
PS100 or CH100.
