My K5 is staying powered on when ignition is switched off. I have checked with a multimeter that the switched 12v to the converter is 0v, which it is. I have replaced the converter and fault is the same. It was professionally fitted 03 / 22. Has been fine up to now. Any advice please. Thank you.

Could you connect the yellow wire to the battery postive with the red wire and see how the DC converter light flashes.
If the DC converter is fine, then it should flash.
Then please disconnect the yellow wire ,keep other wires connected and see how the DC light flashes.
If the DC converter is fine, then it should stay on.
We want to check if the DC converter is working or not.
What happens when the K5 is on and you disconnect the yellow wire? Will the K5 turn off?
If so, a leakage current may be causing the malfunction. You will then have to look for another contact-switched connection.
It takes about 28 seconds for the K5 to switch off after the voltage has been lost on the yellow wire. So the K5 does not go out immediately.
