The 12v items run off the battery, and battery maybe bad or have a switch next to it that is turned OFF? If battery SWITCH is turned ON, check terminal connections/ corrosion and WATER LEVEL in battery cells; (WATER should cover all cell plates and come above the bottom plastic round ring down in the cell) (WEAR SAFETY GLASSES. BAD BATTERIES CAN EXPLODE FROM ANY SPARK); IF you press the TEST button on Monitor panel while plugged in, and it lights all lights for the battery, that generally says the CHARGER IS WORKING; (when UNPLUGGED for 30-60-minutes, a good battery (may) light one bulb less. e.g. 4-lights vs 5-lights)
