CPI 2000 issues

If you have an oscilloscope you should see a waveform on pin 2, not just a DC voltage.

Like I have said I really don't know what I am doing with the scope yet for sure, but Nomad helped quite a bit here, I turned down sweep time/ div to 2 and put the probe on pin 2 on that ic I had replaced and the line rises but I really don't think it really shows a waveform I don't know. The first picture is with the probe off and I had set the line to 0% at the bottom. The second photo is with the probe on pin 2. Perhaps I need to make adjustments

I do see another thing, the 74160 ic on the far right there just gives this on the outputs

Where as the other 74160 ic outputs give somthing that looks more like this

From what I can see you do have a signal on pin 2. I just can't say if it's any good or not. It should be in the neighborhood of 4 MHz or so. Or at least that's what the service manual says.

I went back in the thread and found where the schematic and some service notes were uploaded, but not the service manual, so I'm attaching that here. It can probably answer your questions faster and more accurately than I can.
