Customer Question

Gen will not stay running when start button is released

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

We need to see what fault code is set in the controller.

Go to the genset and use the switch on the set itself.
Press 'Stop' 3 times within 5 seconds. The light in the switch will start flashing.
If the light flashes 3 times, pauses for 3 seconds, and flashes 3 more times, press and immediately release 'Stop' one more time.
This will put the controller into Fault Read Mode.
The light will flash (X) number of times, pause for 1 second, and flash for (X) number of times again. Count the flashes before and after the pause.
This will be the Fault Code.
Example: 2 rapid flashes, 1 second pause, 5 rapid flashes is a Fault Code 25.
There may be more than one Fault Code stored, so watch the light very carefully. If there is more than one code, it will display them all in order, and then start over again.

Be very careful not to misread a first level fault code (single digit code) as a second level fault code (double digit code).
The way to tell the difference is by the length of the pauses.
There is a 1 second pause between digits of a second level code, and a 3 second pause between codes.
For example, if it is flashing 2 times, 1 second pause, flashing 2 times, 3 second pause and repeating, then this is a second level fault code of 22.
If it is flashing 2 times, 3 second pause, flashing 2 times, 3 second pause and repeating, then this is a first level fault code of 2.

Here is what you need to do first.

Connect a meter to the output leads of the genset, and measure the voltage while holding the start button to keep the engine running for a few seconds.

How much voltage are you seeing?

Have you tested the voltage yet?

Customer: replied 21 days ago.
Not sure where to test it at
Expert:  Hank F. replied 20 days ago.

At the output leads. Just follow the conduit to a junctions box, usually mounted right next to the genset, and test in there.
