Posted in: Tech Support

Have you ever tried shutting down your generator from the control panel, but it just won’t stop? The cause of this issue could be a diagnostic switch turned on. Watch the video below and read our FAQs to learn more about addressing this common issue:

1. Why is my generator still running after I’ve shut it down from the control panel?

If your generator is persistently running after a shutdown command, it could be related to the diagnostic switch. Let’s explore how to troubleshoot and resolve this issue.

2. What is the diagnostic switch, and where is it located?

The diagnostic switch is a key component located next to your control switch on the generator panel. It is designed to aid in diagnosing issues, but it should always be in the off position during normal operation.
