On Saturday I got the correct Quad 8-track car radio from Adam. It was working good in all aspects, but I just had to replace the chopped off wiring harness at the internal solder joints (for neatness), which entailed pulling the tuner board....Well the AM band is now dead unless I touch some traces on the board and let my body be the antenna. I'd just about kill for the sams for this radio. I know where the antenna connects to this board, but I don't know how it connects to the AM section (it goes in to the FM section can and has no obvious connection to the AM section). Perhaps the freakiest thing is that I see no obvious connections between the FM section and the tuning mechanism (yet that part works)! I'm beginning to think this radio runs on magic, and I let out the AM sections pixie dust when I opened it....

If anyone can find me a schematic for this Motorola sourced car radio I'll owe you a beer.
