Look at the wiring diagram ... in the side light position the front fog lights will be able to operate, in the dipped beam position both the front and rear fog lights will be able to operate. High beam will not change anything.

Thanks guys just to clarify if I turn the light to the first click and turn the front fog switch on they work but if i turn the lights to the second click (normal lights on) the fogs don’t work is this right then ?

The front fogs should work on both side lights and dipped beam. First and second click.

Silly question, you have got a front fog light switch? Separate to the rear fog lights?

Hi yep I’ve got a front fog switch and a separate rear fog switch, strange I’ll Have to do abit more playing see what’s going on then

Hi

 

can you tell me where is the location for the front fog lamp earth and relay??

because my fuel pump not working and I see the earth for the fuel pump is joined with the fog lamp front 

 

 

Thanks,

It's going to very difficult to explain it all via text.

I think really, you need to grab a Haynes manual and check out the wiring diagrams in the back. They're extremely clear and easy to follow for the MPi. They even pictorially show how relays work. Trace the power with your finger from the battery, to the lights, and all should become clear.

There's 2 main ways to use your multimeter.

Voltage measurement and continuity test.

Voltage measurement is pretty self explainitory. Set the meter to VDC and the range to 20.

Place the red probe at a point where you hope to have 12V. Place the black probe on a earth (the whole engine and body is earthed). It won't work through paint/dirt/grease/rust etc.

Be aware that if both probes are connected to 12V, the meter will read 0V because there is no difference between the Voltage at both probes.

Continuity test, tests if electricity can or cannot flow between the 2 points you're measuring.

Set the meter to Ohms. It should read "1." That's infinite resistance. No electricity can flow. Now put the probes together. It should read nearly "0". Electricity can flow.

To use your earth example above > place one probe on a black wire at the spotlight end. Place the other on a known earth point. If the meter reads nearly "0", you know that black wire is connected to earth.

You can also use this technique to test for breaks in wires/circuits all over the car.

Take a look in the workshop manual.
