Hi,

 

I've won this radio on eBay, late 70's - mid 80's push button AM/LW.

 

 

I am having trouble finding a wiring diagram for the connections.

 

It has a brown wire with a fuse, so I know that is live, a long black wire, a short black wire, and a green wire.

 

 

I know the other wires should be Ground, Speaker + & Speaker -.

 

Anyone have any idea which is which?

The brown fused wire would be a ignition switched live (wouldn't need a permanent live as it has no memory). The short Green and black would be the speaker wires (just the one speaker) with the green being the positive of the two. The long black could be the earth, but that's normally that rusty spade terminal on the back of the unit itself.

Thats very helpful, thank you

Although its hard to tell, that longer black wire could also be the areal connection, with the female plug missing.

Isn't this the aerial socket?

Yes, with the earth spade connection next to it. You could try powering it up out of the car with a spare battery/12v jump pack and leave the long black wire disconnected. Although being only long and medium wave, I don't think it would pick anything up.
