A problem with the Fog Light not luminating
Hi Guys.
I have spent two fruitless hours in the garage. I have been trying to get the fog light to work.
I have used the vickki green wiring loom and the original ford sierra fog light swich. having made a b**ls up of the connections and when i pushed the
swich there was a flash  can the switch be damaged by a power short????
i checked the bulb, its ok, made good the connections to the switch and nothing.
i bought a switch with a light but this has only 3 blades not 4 so the original wiring wont work.
to check the light i took a supply off the battery through the new switch to the and directly to the fog light. the switch on the light went on but no
fog light.
options are
a dead earth ?
a dead bulb ?
a bu*****d ford switch?
a fault in the Vickki green Loom?
have any of you got any further ideas?
How does the three spade switch work?
is there any other way to wire the light?

Souns very similar to a prob i had in the mini. Try checking the wires on the switch. If the light for the switch is wired wrong the current will only
light that and not the fog light. The two lamps need to be in series as opposed to being in parralel. That way they both have to work at the same
time. Although if one breaks both go out. Not that checking it's hard.

wutgout seing a circuit digram or knowing how you have wired up its is hard to diagnose
form your description is sounds like you have the wiring so the switch connects 12 V to ground - hence the flash.
you may have blown a fuse if there is one in the circuit or damaged contacts inside the switch, so I can answer one of your questions - yes, there is
a chance the switch is damaged.
when adding new circuits, always check the wiring using a dvm (less than £5 from maplins) before powering up; once powereed up, check you have
votlages in the right places before flicking the switch.
if you are unsure, temporarily fit a single strand of mains cable in the circuit that would act as a fuse - works out cheaper than blowing fuses (ask
me how I know that!)

To Close out
well the problem is solved. having spent meny fruitless hours in the garage, i was about to give up and pay some one.
i have bought a new swich, remade all connections and well every thing i could think of. then i said to my self what if i reverse the wiring as shown
in the wiring diagramme, and hey presto light
feel much better.
many thanks for the help.
