R3DG3CKO ROB Posted April 25, 2013 Share Posted April 25, 2013 Hi guys, I've added the rear light PCBs that Heckler sells to turn one of the brake lights into a fog when needed. One side has worked fine but the light I've used as the fog light on the drivers side isn't working as a brake anymore (when the switch is off obviously) It comes on when the lights are on and works as a fog light when the switch is pressed but I'm a bit baffled as to why it's acting differently to the other one. They are both wired up exactly the same and I wondered if anyone who's done this had a similar problem? http://www.mkivsupra.net/vbb/showthread.php?253183-Rear-Fog-light-PCB/page10 Quote Link to comment Share on other sites More sharing options...
Steve Paine Posted April 25, 2013 Share Posted April 25, 2013 Pm Heckler I'm sure he will explain and resolve the issue! Quote Link to comment Share on other sites More sharing options...
Kaan W Posted April 25, 2013 Share Posted April 25, 2013 Yeah I had this same problem with my lights, turns out the fog light pcb was the wrong way round or the wires needed swapping I cant remember. Compare it to the one that works and you should see Quote Link to comment Share on other sites More sharing options...
R3DG3CKO ROB Posted April 25, 2013 Author Share Posted April 25, 2013 Yeah, that's what I thought but they were wired exactly the same I double checked that just in case - I've just swapped the PCBs over to see if it makes a difference and the problem has gone to the other side which would indicate it could possibly be an issue with the PCB rather than the wiring? I'll PM Heckler and see what he thinks. Quote Link to comment Share on other sites More sharing options...
Pulley Posted April 25, 2013 Share Posted April 25, 2013 The diode is probably just wrong way round Quote Link to comment Share on other sites More sharing options...
