today I fit a new reverse light switch to our Mondeo. After connecting everything back up including battery reverse lights work. But headunit didn’t. Headunit is an old Kenwood double din so I assumed it had just packed in. Tried another headunit. Not working. Tried another not working.
Headunits power up and receive power fine but nothing works on them. Lights come on and then turns itself off after 3 seconds.
So upon getting hone home I removed the one out my Land Rover and fit it. Worked no problem. I then disconnected it and went to feed it all through the cage , did so and then it would turn on. FFS!
Plugged it it back into Land Rover and won’t work. FFS again!
Is it possible my mondeo is just killing headunits?
