Check Fuses and Circuit Breakers
 

• Locate the fuse box and circuit breakers associated with the onboard generator. Check to see if any fuses are blown or if any circuit breakers have been tripped. Replace or reset them as needed.

 
Consult the Owner's Manual
 

• Refer to the vehicle's owner's manual for any specific troubleshooting steps provided by Ford for the onboard generator system. This can provide model-specific guidance.

 
Verify PowerBoost System Settings
 

• Ensure that all the settings related to the PowerBoost system are correctly configured. Check that the system is turned on and set to the appropriate power output level for your needs.

 
Check Software Updates
 

• Verify if there are any software updates available for the vehicle’s onboard systems. Sometimes, firmware updates can resolve issues with systems like the PowerBoost generator.

 
Test with Known Good Load
 

• Test the generator with a known good load to determine if it's an issue with specific equipment or the generator itself. Use devices you know to be functional to check the output.

 
Examine Engine Condition
 

• The PowerBoost system in a Ford F-150 is closely tied to the engine's performance. Ensure that the vehicle’s engine is running smoothly and that there are no performance issues. Check for any warning lights or error codes.

 
Consult a Professional Mechanic
