Hi all!
The white one is still going strong. However, last night the main beam would not come on. Headlights work OK, but no high beam/ dip.
Any thoughts before I start investigating? I noticed the blue/white wire at the "combination switch" connection, below the dashboard was hot.
I guess I shouldn't have said I've never had any trouble with Lucas...
Tommy.

Solved!
White and blue wire connection had broken at the indicator/ horn/ main beam switch. I had a working spare one, so fitted that one. I'll save the broken one, as well as the other four broken ones I have...., as I believe they can be repaired.
Well, no big deal. What could one expect after 44 yrs?
Going out for a trip with it today, including a ferry crossing. Hope he doesn't get sea sick:-) The winter has returned, but the roads are more or less dry and salt free.
Regards, T

If a wire is hot it either means there is too much current flowing or the wire has become high resistance through fraying /bad connection. You could put an ammeter in series with the battery and measure the current with (a) sidelights (b) headlamp dip (c) headlamp beam (ignition off). If the current doesn't increase more than (a) with the beam on then there is a break or if it is excessive (should only be a little higher than (b)) there is a short that's insufficient to blow the fuse. You could jump from the fuse (not battery side) to the beam wire to see whether the break is under the bonnet or up to the column switch. A quick calculation (V*I=W) will let you know if the measured current is about right, too low or too high. If it turns out to be the column switch and you do not have a spare then it may still pass enough current to operate a relay. I think it is a good idea to operate the headlamps both dip and beam with relays to preserve the switch contacts as they are not the toughest. good luck! David Hi all!

Fixed it the same day:-) Works well now. Some day when I have nothing else to do (hah!) I'll install relays for headlights, HRW and so on.. No wonder these switches give in after carrying loads of current for decades. Regards, Tommy |

Glad to hear you got it sorted _b
Could have been worse like my old BGT, driving down a country road, 'I think I'll put the high beams on' *every light on board goes out* lol
