Thanks for the input and suggestion.? I was trying to figure out a safe way to do some troubleshooting.? I say safe because I am a mechanical guy so I don't always understand the test results I get and I worry about taking my failed electronic item and turning it into a worthless electronic item because of shorting something out, etc.? Electrical/electronic is my weaker suit.? It is much easier with mechanics, you see the leak, etc.? HiHi.
Anyway, I did use a DMM and read out the Amp 15 pin connector on the back of the 3000.? I was pleased to see it appeared okay and the 3000 out was as expected.? Then I looked for continuity on the five conductors of the Plug & Play cable.? There was continuity on all five between five pins on the 15 pin and the 5 pin on the other end.? However, I was surprised to see the match up of the two ends.? I would have expected a different match-up, unless I am reading/viewing this incorrectly.
Finally, I took the RCA relay cable I had between the ARB-704 and the amp relay jack and went from the FTdx 3000 "Tx Gnd" jack and the amp Relay jack.? The amp keyed on transmit.? Based on this I am leaning to something wrong in the interface (ARB-704).? It does have several transistors and diodes.? I thought I would try and test them,
Again, thanks for the dialog and advice.? Attached is a synopsis of my testing to date.? Take care.
