Thanks for your help Gary, it really helped me. Boy I think almost everything that could be wrong was wrong with this thing
1. I opened the cable, and the hot wire was not soldered on.
2. The hot wire was on the 1 having 2 and 3 soldered together
3. They had used a string of solder to connect 2 and 3..
4. My MIC was dead, I had to get a new one.
5. The potmeter on my psr-3000 was loose, so I had to push it quite hard to make it work. First it only worked while I pushed it in. I think this is something I will need to repair in the future...
