I've lost my tail / dash / fog lights. I've checked all the fuses and found there is no power at the "taillight" fuse. I assume this should power up when the switch is turned on.
It could be the switch but the headlights still work so at least that part of the switch is OK.
Does anyone have a wiring diagram or know what is meant to power up when the switch is turned on? Is there a relay or something somewhere? Any help would be much appreciated!!!

Re: No power at tail light fuse
Don't assume the switch is good just because the headlights come on.
If those are on a seperate fuse from the headlights then it means a seperate circuit. That means a seperate 'pole' within the switch for the tail lights, dash etc.. It's entirely possible that pole of the switch is bad, or a connector at the switch has come loose, etc.
However you're going to need a wiring diagram to know if the switch is 'upstream' of that fuse or not.. If the switch comes after the fuse
batt --- fuse --- switch --- lights
Then the problem is somewhere between the fusebox and the battery, perhaps inside the fusebox itself.
Are you sure you are measuring from the correct side of the fuse connection? Actually if the entire circuit is good, you should be able to measure 12v across the fuse terminals when something running off that fuse is turned on.. Depending on the arrangement of the electrical, there's other tests you can do at that point to determine if an open connection exists 'upstream' or 'downstream' of that point.

Re: No power at tail light fuse
Thanks Tempus, yes definitely no power at the fuse - either side. The fuse box and any plugs I can find look OK too.
You're right about the wiring diagram, knowing when there should be power at the fuse is pretty critical to give me somewhere to start. A wiring diagram would also tell me if the stalk switch activates a relay which could be possible given the amount of things the switch turns on ie tails, parkers, dash, fog light controls.
