Lucus - Prince of Brightness? 1967 XKE Series 1

Finaly found the problem. It appears that when I was chasing down an ignition fault I put a fuse not in the pronged holders but in the space above. (yes it fits). This has the effect of turning two circuits into one resulting in very strange symptoms.

I checked with some club members and they had done the same thing at one time.

Note to self: wear glasses and use a flash light.

Thanks for the help. It would appear that either the flash to pass switch or the high beam toggle switch are to blame.

Trim...yeah.....one of the reasons I asked if he'd done anything to the car just before this happened. If the pushrod has worn at an angle, or the tip broken off, and the end of the lever is jammed against it.....all sorts of things, but it's probably in the flash-to-pass, electrical or mechanical.

It sure does but I would check the trim parts first--if they shift it will hold the switch on--more likely than a melt down.!

Dave's guess sounds good to me. I just tried the "flash-to-pass" on my '63 FHC and it did operate although the ignition and light switches were off.

I am not out in the shop yet today. However, my first thought would be "flash to pass", stuck, shorted internally, melted.
Just a guess......but that bypasses ignition switch and headlamp switch, does it not?

My first question would be what did you just do to the car?
Repair/replace/adjust anything?
