I'm wanting to test the AM radio on my 65 Valiant. The light comes on but no sound or buzzing. Right now I don't have an antenna hooked up to it so I don't know if it makes a difference. The wiring is hooked up right but I haven't tested anything yet. I remember we tested it out of the car to see if it worked. We used a speaker and an old coat hanger and it worked clear. It's got two wires to plug into the harness and two wires going to the speaker. I've got a new aftermarket replacement speaker. I'm debating on whether to buy the expensive and hard to find original antenna or a $10 universal replacement at the parts store that even looks very similar in appearance to the original just so I can get it working. Now this is the only accessory that doesn't work. Of course from other posts you'll notice my wipers work but aren't adjusted. I'm just trying to get everything functioning on the car.
