Hi. I have a flashing red light on my alko atc, when connecting to the car it makes a noise and tries to go green but flashes red again. Any thoughts on what i can do to get the lights to go green again. I've tried to unplug it for a few seconds and replug in again, but still no joy. its in storage at the moment so not sure if its ok to move it.
Thanks in advance.
