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

What is the full model number of the genset?

The single most common cause of this issue is that the set is no longer producing electricity.

The first thing you need to do, though, is to check your oil level and make sure it is full.
Low oil pressure will also shut the set down.

If the oil is good, remove the control panel from the front of the genset.
Set your meter to ACV.
Connect the black lead to a good ground.
Connect the red lead to the back of the circuit breaker (either one), on the terminal farthest away from you.
Press and hold the start button for 6 - 8 seconds, and note the voltage.
How much voltage is there?

Good evening, sir. I was just checking in to see if you have had the chance to test the voltage yet.

I have been unable to test the generator. I will try this weekend. It has been very cold here with snow. Sorry for the delay. Peter
