AM Radio


The RADIO Fuse provides main voltage to the Radio. With the Ignition Switch in ACC or RUN, voltage is supplied through the RADIO Fuse and the YEL (43) wire to the On/Off Switch in the Radio.

The Radio is grounded at the Busbar ground. Two wires connect each front and rear speaker to the Radio. The ETR Radio has two input that other models do not have: Display Dim Signal and Clock/Memory Power.

The ETR model is an AM/FM Radio that changes stations electronically. the frequency of pre-selected stations can be stored in the electronic memory. The ETR model also provides a digital display of time or station frequency. As in other models, the Light Switch and Panel and Dome Lamp Switch controls panel light dimming. In the ETR model, dimming of the station and clock display is controlled inside the Radio itself by means of the Dim Display Input Signal.

The ETR Clock memory and Radio memory functions are provided voltage at all times through the HORN-DM Fuse. If voltage to the ETR model is cut off - by disconnecting the Battery, for example - the operator must reset the memory functions when voltage is restored.
