PDM25 - Shuts off when disconnecting USB-cable
Hi, I have just installed a PDM25 that i purchase a year ago and has a annoying problem that needs to be solved.
PDM shuts off as soon as i disconnect my USB cable from computer.
Read in another thread that there could be a issue with "12V ignition input" that has a rail over to the 5V when USB isn't plugged.
Checked that I had 12V in connector C pin 3 and all seems fine. (connected to battery after main switch).
My first thought was that there is something wrong with the rail between 5V and 12V ignition input.
Do someone know what to troubleshoot next? Is there something in software that needs to be adjusted?

No, we have nothing connected to 5V output (C10).
