Be careful that the positive battery terminal does not or will not touch any metal parts of the
vehicle.
Fault Monitoring Installation (ETX Hundred Series)
The ETX Hundred Series batteries have a discrete output that can be connected to many aircraft
Electronic Flight Instrument System (EFIS) electronics or to a remote mounted LED. The
diagrams below detail the required connections for both type installations.
Installation of the battery in the cockpit is not recommended, unless the battery is properly vented
over-board.
To test the internal LED and or external LED, touch the fault monitoring wire to battery negative.
The discrete output for external fault monitoring is a single wire
with ¼” quick connect terminal.
The ¼” quick connect terminal is an insulated “female” type and should be compatible with most
other manufacturers insulated male ¼” quick connect terminals.
The following two examples detail
how to connect the fault monitoring output to an EFIS general purpose discrete input. The EFIS
DC source negative must be referenced to the battery negative (this is the standard configuration).
