Questions and answers
HOW DO YOU MANUALLY TURN IT OFF AND ON WHEN YOU ARE CHANGING BOTTLES OF PROPANE
To manually turn off and on the Briggs & Stratton GC1031 when changing propane bottles, follow these steps:
1. Turn Off (Manual Shutdown):
- Press the “OFF” key on the controller to stop the generator.
- Wait for the generator to completely stop before proceeding.
2. Change the Propane Bottle:
- Ensure all fuel valves are closed.
- Replace the empty propane bottle with a full one, following safety procedures.
- Open the fuel valve after replacement.
3. Turn On (Manual Start):
- Press the “MANUAL” key to enter Manual Mode.
- Press the “START” key to crank and start the generator.
- Observe the generator to confirm it runs normally.
Always follow safety precautions and ensure the generator is stopped before servicing.

I have a GC 1031 - R8.00 Briggs and Stratton generator. I t has only 54 hours of operation on it and engine status is healthy. I had it running for 12hrs or so and then turned it off overnight. When attempting to start it in the morning I first got an l/p sensor alarm. I cleared the alarm on keyboard and attempted to start it several times. It cranks for a second and immediately stops and won't turn over. Not sure how to remedy this???
The cause of a low-pressure sensor alarm and starting issues with a Briggs & Stratton GC1031 generator could be due to low voltage during auto-exercise, loss of alternator input, or low ambient temperature causing the auto-exercise to be skipped. These conditions can prevent proper startup and trigger alarms.

auto start skipped
The auto start on the Briggs & Stratton GC1031 may have skipped because the genset was in Auto Exercise Mode. During this mode, the genset will turn on even if the mains power is healthy, but the load will not transfer to the genset, even if "Load transfer is enabled" in the configuration. Additionally, the controller will enter LIM (Load Inhibit Mode) after the first 6 seconds of Auto Exercise Mode, which could affect the auto start process.
