Problems with lights on Jaguar E-Type 1970

Hi Stef, When that happens on mine it is in the switch itself. On mine repeatedly turning it on and off a few times makes it work. (I should really replace it).

You can test if it is the switch > Hello,

Q: Why do the British drink warm beer?

A: Their refrigerators were made by Lucas

Hi,

inetcaster a pensé très fort :

Thank you. I tested the switch by touching the wires together. Crossing lights work, but road lights don't work.

I think there is a relay in another place. But I don't know where I can find it.

Be sure to check the fuse. In fact I would try replacing the fuse even if the one you have looks OK. It seems that the original British fuses were made with fuse wire rather than a shaped conductor. The wire is attached to the indented end caps with a drop of solder. What can happen is that the solder can melt and drip off, leaving the wire in loose contact with the cap. It will pass a small amount of current, but look like an open circuit to a heavy draw. It happened to me on the circuit that runs the fan motors and horn relay. The horn would blow, but the fans wouldn't run (equalling an overheating engine). I found the problem when I burned my fingers removing the fuse (Yes - it was HOT!).

BTW - I have a '70 E-Type Coupe.
