Ground Connection
The IBI uses a ground reference to operate its control circuitry which it reads through the Ground
Connection. To set up this connection:
1. Prepare an AWG18 wire with a #10 lug on one end.
2. Connect this end of the wire to
Ground Point
.
3. Connect the other end of the wire to the battery negative terminal or directly the engine block. If the
ground is properly connected, the
Grounding LED
will be illuminated. This is a very high efficiency
LED that requires only 1 milli-amp from 12 volts so it will never discharge the battery.
Ignition (IGN) Connection
The Ignition (IGN) Connection is an optional connection done by the installer. If you read a normal
charging current from your alternator to the battery banks after installing the IBI then you do not need
to make this connection.
If there is no charging current after installing the IBI, you may need to make an Ignition Connection.
Simply attach the original charging wire back to the alternator using a commonly available industrial
axial leaded diode such as a 1N4001 with the cathode (bar end) facing the alternator. The diode will
apply voltage from the battery to the alternator so it will start.
