It is very important that all wire extensions are well connected, to ensure the
stable and reliable operation of the product. For your convenience, butt splice
connectors have been provided. After a secure connection is made, use the heat
shrinkable tubing or electrical tape to completely cover any exposed wiring to
prevent a short to surrounding metal.
Notes:
• Disconnect the negative battery cable (Earth) from the vehicle’s starting
battery before installation.
• If your vehicle has a fixed voltage or temperature compensating alternator
(standard alternators) installed, leave the Ignition Override cable (BLUE
color) open. If your vehicle has a smart (variable voltage) alternator
installed, the Ignition Override cable must be connected to the vehicle’s
ignition. The Battery Charger will only operate when the vehicle’s ignition
is turned on.
