TROUBLE SHOOTING & FAULT FINDING
* ATC stores operating errors in a logle which over time will become full and will result in the solid red light appearing. This needs to be erased and can be done easily by
connecting the caravan to a 12 volt supply for a period of 12 hours. The power required to carry out this function is minimal. Most occurrences of these errors are due to
power supply problems to ATC which could be due to low voltage, or an intermittent power supply from the towbar.
