Radio Static

My bet is the radio is not functional...

Tests...

Antenna

With a multimeter on Ohm scale check the center pin in the connector that goes into the radio to the base of the antenna mount. Should be open (OL) on many meters


Next check between same pin and the mast of the antenna. Should read 0 ohms or very close


The (every) speaker has two terminals.
One is for the negative side of the voice coil and the other is for the positive side of the voice coil.

Technically it does not matter which is which but stick with what ever the OEM setup.

On your radio you have:
red wire + 12v
Housing of the radio is ground
Orange that goes into the top of the radio is the light

Green and black, are the positive and negative speaker wires BOTH have to be connected to the speaker.

The fact that you can hear static in the speaker says you have the speaker and the power and ground for the radio hooked up correctly.



When you here static and you move the tuner or volume does the static change?

IMHO unless there are no AM stations in your area (unlikely) and your antenna is good, your radio is bad.
