Fault Monitoring Connection to Grand Rapids Technologies EFIS
The following example details how to connect the fault monitoring output to a remote 12V LED.
The positive wire (anode, typically the red wire) of the LED should be connected to the electrical
bus (positive), and the negative of the LED (cathode, typically the black wire) should be connected
to the fault monitor wire (wire out the side of the battery) of the battery. It is recommended to
connect the positive of the LED to a fuse/breaker downstream of the master switch. 20-22AWG
M22759/16 or similar wire is also recommended.
