Hello, my name is ***** ***** I am going to assist you with this.

You didn't give a model or serial number, so I am going to assume this is an air cooled unit with an Evolution controller.

If so, error 1505 is RPM sense lost. It means that the controller is not able to sense how fast the genset is running.

If this unit is only a year old, your best option is to contact a certified Generac repair facility to have this repaired under warranty.

If you decide to try and work on this yourself, you will void your warranty, and will be responsible for the cost of any parts needed.
