I have a Kohler ATS model: RTS 100-400 amps. I noticed after a power outage that my generator would not turn off. I look downstairs on the control panel inside the house that the no LED lights were on. Usually when power comes back on it switches over automatically after a cooling period this time no lights were present. The only way I was able to shut down my generator was from the unit itself (off position) on the switch.

Any idea what would cause the LED panel to not light up? The unit is about 15 years old.

The controller may have gotten hit by lightning. I'm not a Kohler guy, but if there are any fuses in the switch, make sure to check them!
