Earth strap fuse on 6v Lambretta.

What amp fuse would I use for the earth strap? Thanks

Why do you want to put a fuse on the earth strap? Not heard of this before.

Just realised I don't need one. Thanks for the reply Tractorman. I have a problem with the rear lights. Just eliminating potential problems. The fronts are fine but just found out the horn is buggered.

Have you made sure the earth is good to the rear, a quick check would be to run a wire from the engine earth and touch it to the rear bulb holder when the lights are on, if the rear light goes brighter than the earth to the light is faulty. You could also check the bulb contacts and the wiring connections to the bulb holder.
