Default Troubleshooting audio system

I am trying to determine where and when I should have have voltage at the speakers and the speaker switch on the control panel of my ‘09 Ultra.

I need a printable diagram or something to reference.

The radio was intermittent, I could toggle the switch and it would work for a bit and then drop out again…now I got nothing. I have voltage at the switch but not sure it is where it should be when toggling.

Should I have continuity between the switch and the speakers?

Help! Thanks in advance.

When you have nothing is the radio lit but no sound? Or it is dark as night?

Default Bad head unit

Going to say you have a bad head unit. Not that uncommon. But here is the schematics.

Just an FYI when checking voltage at the speakers and switches the signal is
AC VOLTAGE.. going to the speakers.

When diagnosing the output of the system use a steady 1k hz test tone so there is little to no variation
