What to do if there's no output voltage and the status LED is red on my Xantrex Freedom hf 1800?

If the Xantrex Battery Charger shows no output voltage and the status LED is red, possible causes include AC shore power issues, low or high input voltage, unit overload, short circuit, or thermal shutdown. Check DC connections and cables, recharge the battery, verify the unit is connected to a 12V battery, check the voltage regulation of the external charging system, reduce the load, allow the unit to cool, improve ventilation, and ensure ventilation openings are not blocked.
