It is something to do with the indicator box which on the Mk1 is located under the dash on the drivers side on the inner wing panel I think.

Try adding a temporary bridging lead from the lamp body to a good earth.

Hello Pete,

it may be a fault in the flasher relay. The MK 1 system is relatively complicated, the flasher relay is a change over type rather than a simple open and shut contact and the change over contact only feeds the indicator tell tale lamps in the instrument cluster. If there is a bad contact within the relay or a poor connection downstream of that could give your fault?
Do you have a diagram and or a meter to be able to do some checks?
