The green LED marked Status2 is used in lithium mode. It blinks to indicate the number of lithium cells detected. Also, when Status2 and Error are flashing at the same time, and you are experiencing no output from the motors, the unit is displaying low voltage mode. Charge your batteries first, and if that does not work, you will need a larger battery. Keep in mind that when a lot of current is pulled from a battery, the voltage will drop. The more depleted the battery, the worse the voltage drop. The Sabertooth will hold the unit in the error state for longer than the battery voltage drops. This is to stop the unit from stuttering and gives the user enough time to diagnose the flashing LEDs.The red Error LED illuminates if the Sabertooth has detected a problem. It will light if the driver has shut down due to overheating or overcurrent.
So if the TBS is fully loaded with sounds, when connected each slot looks blank? That is what I see ..or don't see lol after it connects.
