1966 Lemans Dash Speaker

[Shep1966]

I have a 1966 Lemans Convertible with the original factory AM radio and dash speaker. I have power to the radio but can't get any noise out of the speaker not even static. I haven't got under the dash to look at the wiring yet, but does anyone know where I can get a diagram of the wiring from the radio to the speaker so I can troubleshoot? I want to get this working before I look into a replacement radio. I don't want to cut holes into any of the side panels etc so I may just take a bluetooth speaker with me when I want to listen to tunes

Thank you

Not really complicated wiring to a speaker, two wires. Use a 9 volt battery to test speaker and voltmeter to test harness.

They make really good bluetooth units now that look like original and no cutting of panels/dash
