What to do if my Generac Power Systems Portable Generator is running but has no AC output?

If your Generac Power Systems Portable Generator engine is running but there's no AC output, check the following: 1. The circuit breaker might be open. Reset the circuit breaker. 2. There may be a poor connection or defective cord set. Check and repair the connection or cord set. 3. The connected device could be faulty. Connect another device that is in good condition. 4. GFCI trips the 20 Amp outlet. Repair the "short" and reset the GFCI. If these steps don't resolve the issue, there may be a fault in the generator, and you should contact an Authorized Service Facility.
