Hello and thank you for using Just Answer. My name is ***** ***** I will be assisting you with your question. I am sorry that you are having issues with your GM. On your low air alarm. As long as the light is not on when the buzzer is supposed to be then that is an indication of a failed pressure switch, or in the wiring. There is an air pressure switch that is supposed to close when the air pressure drops below 60. Most of the time it is either an issue with the connector at the switch or the switch itself. On the switch you can test it by having the tanks aired up and using a multimeter on the switch, then drain the air out and see if the switch closes when the pressure drops down. If it does not then you will need to replace that sensor. Please let me know if you have any follow up questions on this. Thank you and have a nice day.
