Hi , just spent an hour getting the rusted 17mm nuts off with a blowlamp(and a spanner) to release the front fog lights on my classic as they dont work.

I was hoping it was just a bulb but they are both ok as I have tested the on the battery direct.

I have checked the fuses and they are ok and I have checked using the bulb and crocodile clips to see if there is power coming to the Lucar connectors for the lights and there is none.

Is there a usual place where these fail and if so how do I fix them?
 
did you make sure you don't have the high beans on? remember that the fog light only work with the head lights on but not the high bean. Is that is ok you should follow your cables to see if one of them is broken.

beans :confused2: is that summat new with fog lights :p:p
 
Yeah highs were off and lows were on.

I looked briefly at cable runs but couldnt see much as thers so much crap in the way, thats why I was hoping you guys had some clues on where to start:)
 
What year classic? mine was 89 and had lamps in front spoiler as standard but were driving lamps not fog lamps and came on with high beam not low, my mates classic was the same. I guess you did check it before you started. (been there done that got the tee shirt and sore a--e from kicking my self for not checking properly in first place)
 
I wish I knew if there were any relays, thats what I am asking really. I will get out there and have a look if it stops pisin it down at some point lol.

I have a switch for them on the dash and my 1990 handbook calls them the fog lights but I will test your theory today!

Sir you are correct:clap2:

With the switch depressed and the lights on full beam both the front fogs work! Thanks you for saving me hours of wire chasing!

One question though , whats the point of having the fogs on with full beam only? as you cant see in fog with full beam on as it reflects back on you!

No (for once!) They are classified as driving lights, not fog & a lot vehicles were wired like that at one time (& maybe still are) something to do with legislation. I drove new HGV's in the 'eighties that had lights wired in the same manner.

You may also find that when you put your high beams on the rear fog light goes out. I thought mine (86) had a fault until it was pointed out that this was also normal on the RRC.
And as you now know, the lamps on the front aren't fog lamps.
 
That does seem pretty pointless all round though, and no dedicated front lights either??

What an outdated system for 1990 vehical, no wonder we are run by India now!
 
Glad to be of help fett, I put pair of cheap round spots above bumper and pulled wire up to feed them instead, sure improved main beam performance. rewired original lights through relay and seperate switch to come on with dip beam if needed.
 
I have fitted some relacement main headlights from Paddock,supposed to give 60% more light. They are better than I thought at first and they were only £22 and drop straight in.
 
For wot its worth, the beam pattern is totally different too. Fog lights give a low wide beam with little distance. Spot (driving) lights give a narrow, far reaching, pencil beam.
