IN CASE OF DIFFICULTY
Low Voltage Disconnect trips under high demand conditions
This can be caused by 2 things. First ensure your battery is charged. A discharged battery will
recover voltage under low current conditions, but once current is drawn it will immediately drop
below the cutout voltage. Second, ensure the wiring on the input side of the unit is adequate for
the current being drawn and the lengths of the cable run.
Enable LED fails to illuminate.
Ensure that you are either feeding one of the enable lines from the radio amplifier key line into
the unit or the Enable/Disable switch is depressed.
Minimum Battery Voltage
According to battery manufacturers vehicle batteries are normally considered drained at 11.6V
with no load. Under load the voltage will be a little lower. Below about 9-10V the voltage will
drop fast with any load. The battery life may suffer and the vehicle may not start when the
battery is that low.
