Briggs & Stratton Power Products Home Generator
Owners Manual
Low Battery Voltage
This fault is indicated by one blink.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 trickle charger circuit.
To remedy the problem, contact your local service center to check the battery trickle 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 the battery after it has been fully recharged, connecting the NEGATIVE cable last. Install the 15 Amp fuse.
Low Oil Pressure
This fault is indicated by two blinks.The unit is equipped with an oil pressure switch (Figure 4) using 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.
Engine Fail To Start
This fault is indicated by four blinks.This feature prevents the generator from damaging itself if it continually attempts to start in spite of another problem, such as no fuel supply. Each time the system is directed to start, the unit will crank for 15 seconds, pause for 15 seconds, crank for 15 seconds, pause for 15 seconds, and repeat. If the system does not begin producing electricity after approximately 90 seconds, the unit will stop cranking and the LED will blink.
The most likely cause of this problem is no fuel supply. Check the inside and outside fuel shut off valves to ensure they are fully open. Other causes could be failed spark plug(s), failed engine ignition, or the engine air filter is clogged.You may need to contact your installer for assistance if you can’t remedy these problems.
Low Frequency
This fault is indicated by 5 blinks.This feature protects devices connected to the transfer switch by shutting the generator down if the engine runs slower than the preset limit.

To remedy the low oil pressure condition, add the recommended oil to the FULL mark on the dipstick.
If low oil pressure condition still exists, engine will start, then shut down after about 10 seconds and diagnostic LED will flash. In this case, contact an authorized service facility.
Low Voltage (Generator)
This fault is indicated by three blinks.This condition is caused by a restriction in the fuel flow, a broken or disconnected signal lead, a failed alternator winding, the control panel circuit breaker is open, or Home Standby Generator is overloaded.
To remedy the problem, contact your local service center.
This condition is caused by a failed engine governor or by excessive loads on the generator.To remedy the problem, you may need to contact your installer or local service center for assistance.
Engine Overspeed
This fault is indicated by 6 blinks.This feature protects devices connected to the transfer switch by shutting the generator down if the engine happens to run faster than the preset limit.The overspeed fault is detected as follows:
•If the generator output frequency runs at 72 Hz for five seconds, the generator will shut down.
•If the generator output frequency reaches 75 Hz, the generator will shut down instantly.
This condition is caused by a failed engine governor.To remedy the problem, you should contact your installer or local service center for assistance.
Oil Temperature High
This fault is indicated by seven blinks.The contacts of the temperature switch (Figure 4) are normally open. If the engine oil temperature exceeds approximately 140°C (284°F), the fault is detected and the engine shuts down.
Common causes for this condition include running the unit with all access doors removed, obstructed air inlet or exhaust port, low oil level, or debris in the engine cylinder cooling fins.
To resolve the problem, remove any accumulated debris and obstructions and let the engine cool down. Ensure that the Oil Service door and/or the Control Panel door is installed whenever the unit is running.
