Battery Selector Switch
In vehicles with a Battery Selector Switch, the ignition sense (yellow) wire should be the only wire
connected to the Battery Selector Switch. The radio transceiver and control head power wires (red)
must be connected directly to the vehicle battery. If the control head power wire and the control head
ignition sense wire are both connected to a Battery Selector Switch, but the radio transceiver power
lead is not, improper power-cycling and off-state battery drainage may occur. If the desired state of the
radio is a total battery drain elimination, then route all power and ignition sense wires through the
Battery Selector Switch, so that the control head and radio transceiver both see the loss of battery
power at the same time.
