Audio unit and road noise

[Camohurley]

Also something I'm not understanding is the antenna cable supressor when plugged into the back of my radio it gets rid of alot off the noise but the radio is just extremely staticcy is that because it's interfering the signal from the fm transmitter?

Well....the relay didn't work either still clicking.

 

[Camohurley]

It seems like even with bypassing all factory wiring I still have the interference on two separate radios

Where are the radio grounds going to? The original harness? Or grounded somewhere under the dash?

Try taking a jumper wire and ground the radio straight to the battery. Seems like the other accessories are backfeeding into it for some reason.

Is this a 12v or a 24v truck?

All grounds are into the metal dash. It's 12v.

With the ground for the radio and the 12v supressor straight to the battery no change.

Is it possible I just have two bad radios? Does anyone know where I can get a factory am only radio in working condition? (Or at least one that is fully analog wife doesn't wanna any digital screens)

Ok so your saying I should get a relay and wire it to my battery and to the radio and then run the original power wire from my radio unit to the relay to engage the relay correct?

Yes sir. 85 ground, 30 battery, 86 original radio 12v source 87 to radio.

I tried that out no luck. I connected the radio to my battery in my 2013 and no clicking so I don't think it's the radio. Did those trucks by chance have a ground wire that went to the fuse box? The wires in this thing are all jumbled and effed from the fire department and the owner before that was a farmer. Stuff has just been cut out and spliced in as needed. But it seems like the only other thing I can guess would be a short in the fuse box somewhere sending all electrical signals to the radio instead of to a proper ground

Direct power from the battery should cut the rest out and 86 and 85 go to the coil in the relay 30 and 87 are direct once the relay is activated.

With the relay hooked up and all internal wireing bypassed it still has electronic feedback

I am so confused right now

Also with everything ran straight to the battery I still get the electric noise and when I turn on headlights it gets quieter. The other thing idk if I mentioned is the buzzer that says fasten seatbelt also comes thru the speaker upon ignition

One more thing guys I got my buddy's truck and plugged the radio in full with the antenna cable no issues prior to this and it did the same thing...could the port you plug the antenna into go bad on these?

 

[Camohurley]

Is there supposed to be a second wire here? Also sorry for all the posts just losing my mind
