[QUOTE="PNotts, post: 8704193, member: 679620"] Good Morning, I hope you are well. I need some assistance please with my head unit in my card, a Ford Mondeo 2009 TDCI. Recently the factory installed cd6000 started switching off, aux not working , so as it was on its way out I thought I'd change it. However I am having even bigger issues with my Android Head Unit now. When it's plugged in it drains all my battery but this doesn't always work either and switch on. I read somewhere that cutting the permanent live is a good way of stopping the drain but I'm also worried about it not switching on all the time so think there is more to it. Yesterday I took a multimeter to the power pins to see what is coming through. I was unable to take the pins out but was able to take measurements which are below. Pin 9 - 3.4V (engine on) - 0V when off Pin 10 - 0V on or off Pin 11 - 0V on or off Pin 12 - 0V on or off Pin 13 - 0.68 (engine on) - 0.6 engine off Pin 14 - No cable Pin 15 - 0V Pin 16 No cable The above don't really seem right to me, would I get different readings if I took the pins out and ensured I had a proper connection with the probes? I have never really had anything to do with changing/checking audio so any assistance would be greatly appreciated.
