Hi all,

Just in the wiring loom near the headlight there is  diode. This is encased in black plastic approx 3x2x1cm, with the three wires coming out into a connector to plug into the wiring loom.  Mine has a hole burned through it, as if the diode has heated and burned. (see the photo).
Can someone explain what the actual function of the diode is in the wiring loom, as everything seems to work OK without it.  I know what a diode actually does, but what is its purpose in the TR1 loom? Will it cause problems if it is not working. Should I replace it? If I should replace it, does anyone know the specifications?

Cheers
Richard
