Servicing the System
To service system:
1. Set the system switch to OFF.
2. Set the generator’s main circuit breaker to its OFF position.
3. Utility voltage is present. Disconnect power before
servicing by removing the two 2 Amp fuses from the
transfer switch.
Fault Detection System
The generator may have to run for long periods of time with
no operator present. For that reason, the system is equipped
with sensors that automatically shut down the generator
in the event of potentially damaging conditions, such as
low oil pressure, high temperature, over speed, and other
conditions.
The generator’s control panel has a digital display that shows
fault codes, like “FC_1”. The table below lists the detected
fault, the fault code as displayed on the control panel, and
the number of blinks seen on the remote LED indicator.

The remote LED indicator is installed at a convenient inside
location. The LED will remain lit when the generator is in
AUTO. The LED will turn on and off in a series of blinks that
correspond to the fault detected in your home generator. The
blink pattern is repeated with a brief pause between each
series of blinks.
Reset Fault Detection System
The operator must reset the fault detection system each time
it activates. To do so, place the system switch in the OFF
position for 5 seconds or more. Remedy the fault condition,
then return the home generator to service by placing the
system switch in the AUTO position.
A description of each fault and suggested remedies are as
follows:
No LED - Discharged Battery
If there is a detected fault condition but the LED is
not blinking, this is because the battery is completely
discharged. To remedy the problem, remove the 15 Amp
fuse and disconnect the battery from the generator. Take
the battery to a local battery store for analysis. Replace the
battery after it has been fully recharged, connecting the
NEGATIVE cable last. Then install the 15 Amp fuse in the
control panel.
NOTE: With the battery installed, all wiring to transfer switch
and home generator completed, utility power supplied to
the Automatic Transfer Switch, and the system switch in
AUTO position, the battery receives a trickle charge while
the engine is not running. The trickle charge is not able to
recharge a battery that is completely discharged. See Battery
in Maintenance.
Low Battery Voltage
This fault is indicated by fault code FC_1 and one blink on
the LED indicator. This condition occurs if the generator
cannot start because the starting battery output power is
below that needed to crank the engine. Causes for this
problem may be a faulty battery or battery charge circuit.
To remedy the problem, contact your local service center to
check the battery charge output. Remove the 15 Amp fuse
and disconnect the battery from the generator. Take the
battery to a local battery store for analysis. Replace ONLY
with same type battery as described in Battery in Installation.
Replace the battery after it has been fully recharged, connecting
the NEGATIVE cable last. Then install the 15 Amp fuse.
Low Oil Pressure
This fault is indicated by fault code FC_2 and two blinks on
the remote LED indicator. The unit is equipped with an oil
pressure switch (A).
The oil pressure switch uses normally closed contacts that
are held open by engine oil pressure during operation.
Should oil pressure drop below the 8 psi range, switch
contacts close and the engine is shut down.
To remedy the low oil pressure condition, add the
recommended oil to the FULL mark on the dipstick.
If the low oil pressure condition still exists, the engine will
start, then shut down after about 20 seconds. The fault code
will appear and the LED will flash. In this case, contact a
Briggs & Stratton Authorized Dealer.
