Reviews and Ratings
***Note From BatteryStuff.com***
The red light flashing indicates that the battery charger has AC power available and that the microprocessor is functioning properly. If the red light continues to flash, then either the battery voltage is too low (less than 3 volts) or the output connector is not connected correctly. Some SAE accessories are reversed polarity from Battery Tender products. Since it works with the alligator clips directly to the battery I would suggest testing you polarity of the Auxilary connector as it might not be compatible with the Battery Tender products.
