Based on the test results I'm really starting to think it's a multitude of problems. Unsure what my next step is beside taking the fairing off and dive into every single wire (still plan on running that ground wire to the radio or radio bracket).

 

What changed between attempts?

 

nothing the first couple of times then I tried in different areas of the antenna to see if anything would bring it back. Each time I turned off the ignition switch.

 

ok - so you played with rear lighting wires and it worked ( i suspect you moved another wire and that was the cause) and you grounded the antenna wire and it worked. I would 100% verify radio head unit ground and check the antenna wire for breaks. Keep cable grounded grounded - wiggle it around with the radio on. This really sounds like a wire or connection. I'm starting to suspect a bad radio antenna cable or connection to antenna. Sometimes the cables degrade internally. Push the antenna cable toward the connector that screws to the antenna when wiggling. Also - you said it was cutting out on bumps.

 

I'll need to remove the fairing for that, sounds like a good course of action and great resolution if its the problem. Thanks bud

 

Leave the fairing on - I am talking about the tourpack side of the antenna. If you checked the radio ground, I'm ok with that for this part. I really think it might be a bad antenna cable or bad antenna connector.

Also look on page 57 for the antenna tests (link provided above for wiring diagram from 14 GuineaPig)

 

so basically do a continuity test. I can also try cleaning antenna connector up more too.

 

I added the antenna test page as well in above post. I am really thinking bad antenna cable issue or the connection inside the mount where the antenna threads on.

 

Sounds like a plan, I hope I can do that tomorrow. Starting to feel like making progress.

 

If it were me, I would go out there, and with the antenna cable grounded, push hard/wiggle between the cable and the antenna like you are forcing it together as a quick test. It's very possible that after all these years, the threaded stud connection is bad in the mount. Don't tighten the antenna completely - make it so it's threaded on and you can have a few threads showing and push the stud into the mount.
