James_VW Posted May 14, 2018 Report Share Posted May 14, 2018 Having an issue with the stereo not powering on at all. Tried 2 different stereos, neither work in the GTI but both do in the polo 6n2. Safe to say the stereos are good. Here is a pic of the stereo wires. (unsure what the purple and black wires are, but have no voltage at any stage) I have recorded the voltage of the black plug as I think the brown plug is just for the speakers? I have checked fuses 20 and 46 and and seem good. These voltages are as if you are looking at the black plug straight on. Any thoughts?

James_VW Posted May 14, 2018 Author Report Share Posted May 14, 2018 Measured both. Generic pic found online. Letter L (brown/red) = Lupo has no volts throughout. Polo has 0V at ignition off and 12V at ignition on. Letter I = Lupo has 7V at ignition off and 10V ignition on. Polo has 0V at off and 10V ignition on. Letter J = Polo has no wire. Lupo has green/grey wire So I'm assuming the problem lies with the letter L being there is no ignition voltage. What can cause this? Quote Link to comment Share on other sites More sharing options...
Rich Posted May 14, 2018 Report Share Posted May 14, 2018 maybe an ignition switch issue? Quote Link to comment Share on other sites More sharing options...
James_VW Posted May 14, 2018 Author Report Share Posted May 14, 2018 Wow, embarrassing. Fuse 16 was popped. Glad it was just a fuse... Cheers, anyways Quote Link to comment Share on other sites More sharing options...
