Headlights

[Priglet]

Just curious to see if anyone else has had a similar problem with their headlights.

I changed from sealed beams to 'proper' headlights and shortly after the dim dip stopped working. Now I've also lost dip beam so can either run on side lights or main beam. There's power coming out the back of the switch and the relay still works when I tried it in a different circuit. That seems to be all the easy fixes out the way so it looks like I'll have to try and find the resistor and see if that's gone for a burton.

Check the plug connectors on the back of the bulbs, it's not unheard of for these to melt with higher wattage bulbs, you'll find there is quite a difference in heat output between sealed beam units and halogen bulbs.

Thanks Frank,

Had a look at that and it seems to be alright. I can get power to sidelights and main beam but nothing else.

Have you power to the bulbs, its not unknown to have both bulbs pop
If you have a wiring diagram, check the feeds out of the back of the switch to see if they are feeding, also I presume you have already check the fuses to see if power is going through them and/or the fuse hasn't blown

Thanks for your input.

No power to the bulbs and I've already checked the fuses. I learnt that lesson the hardway a couple of years ago. One headlight was out so I replaced it, still didn't work so then checked the fuse :oops:

I've got the Haynes manual with a wiring diagram so will try to have a look at that.

With the wiring diagram, just back track the feed from the fuse, not sure on the layout on these motors, if the fuse is not getting the power, and the switch is after the fuse, you know you have to look closer to where the power is taken off for the auxiliars, or a burnt wire or connection somewhere, good luck, always good fun

Did you suss the problem then Phil?

[Priglet]

Not yet, still working on it.

At least it's summer so I don't need them much :P

[pirate king]

have you got bullet connectors in the loom?
sometimes you can lose contact on the earth.
That one has messed me about a few times.
Or try the column switches, they are really important to the circuit, in a weird illogical Solihull kind of way.
I had loads of problems with my headlights which I eventually traced to a lose rivet on the contacts of the column switches.
Hope this helps

Thanks for everyone's comments. The problem's sorted now although I did have to resort to an auto electrician as I couldn't find the problem.

It seems that water had got behind the dashboard which didn't do a lot of favours to the electrical components tucked away there. Something made by lucas in a nice pink case and 7 pins, possibly the voltage transformer, had corroded as a result which knocked the lights out.
