According to DIN 72552 the coil should be fed with +12V to terminal 86 and grounded via terminal 85, however in practice it makes no difference which way around they are wired, unless you are using a relay with an integrated diode (see more info on diodes below).
You will notice that on the Type B layout pins 86 and 30 are swapped over compared with the Type A layout. The Type B layout is arguably easier to work with as the connected terminals are in-line, making the wiring easier to visualise. If you need to replace a relay make sure you use one with the same terminal layout as it is easy to overlook if you're not aware of the difference.
As a matter of fact I have not a clue what you are saying. People who really 'get' electrical/electronics feel it is more-or-less quite simple - providing it is not an overly difficult 'project'. I've been restoring vintage Alfa Romeo for a living for 24 years. While I farm out the engine's machine work, I completely rebuild them myself. Though they're 'only' 4-cylinder engines, they have dual overhead cams (which need to be shimmed to tight restrictions). The engines have always run with no problems. That is because I can SEE what I am doing. Among other things I remove all of the electrical components including the wiring looms. I have few problems since I mark everything when removing.
Of course I do know how the XF (Crossfire) spoiler works - in general. When I checked the voltage of the spoiler's motor on the Ltd while opening it through the dash switch, it was 13.5V. The voltage for the limit switches was 12.5V.
bibaRestro said:SS, keep in mind the spoiler switch on the dash in the SRT6 is just a dummy. A couple of things: What is the chime situation? Is it supposed to be a warning chime like a backing up one? I'm quite sure there is no chime for the spoiler;
