Hello!Thank you for choosing Just Answer for the solution to your problem.My name is XXXXX XXXXX I am going to assist you with this.
What is the brand and model number of the genset?
There are dozens of Guardian series 20kW sets - I need the exact model number.
Also, since it is a 20kW, I need to know if the word 'NEXUS' in on the controller, next to the start switch.
The model number is XXXXX a sticker pasted to the left side of the divider that the control panel is mounted to.
It is right next to the front cylinders valve cover.
I understand the situation you are in, and sympathize.
But I need you to acknowledge the fact that since this set is new, it is still under warranty, and without contacting your local Generac service center, anything you do to it may void your warranty.
The first thing you need to do is to check the battery - make sure it if fully charged.
A voltmeter connected to it should read 12 to 12.6 volts.
If it is low, you can try jump starting it with another 12V battery.
Does this get is running?
The battery is inside the genset enclosure - you will need to open the lid and remove the front panel to access it.
But you will need a meter to test it.
