LewLupo Posted December 6, 2011 Report Share Posted December 6, 2011 Every time I start my lupo the power for the head unit comes on for a few seconds with the dash lights then goes out? Tested fuses relays and no problems there ? /: I'm really stuck any help would be greatly appreciated Quote Link to comment Share on other sites More sharing options...
beska133 Posted December 7, 2011 Report Share Posted December 7, 2011 you'll need to explain a little more, but from what i kind of understand, take the head unit out, and on the wiring loom there will be a plus and negative wire which will be obvious because they will have a male and female connector covered in clear plastic insulator, take them off and switch them over, so + goes to - and via versa, hope that helps Quote Link to comment Share on other sites More sharing options...
LewLupo Posted December 7, 2011 Author Report Share Posted December 7, 2011 Thanks I will try that later, After a little more playing around last night I discovered its not just my aftermarket headunit but the standard one doesn't work either /: A little more about the fault.. When I turn the key with my aftermarket headunit fitted it powers up in sequence with the dash warning lights and then goes out with them, but if I press te display button te backlight comes on but still not functioning as a headunit should ? The fuses and relays are fine, and with a tester I tested all the wires at there block ends and only one has a live to it and from what I can gather that's the constant live. Even wheni turn the key there is not an ignition live ? Hope this helps some more Quote Link to comment Share on other sites More sharing options...

bigben Posted December 7, 2011 Report Share Posted December 7, 2011 (edited) Patch a permanent live up? That's what I done to mine when mine didn't work. Just need to remember to turn it off whenever ya get out the car. Doesn't matter to me cos I take the fascia off anyway Edited December 7, 2011 by bigben Quote Link to comment Share on other sites More sharing options...
