It has "CH" "D" "H" "L" on the top . Luckily I bought a top and knob from Arnaud when I was cobbling the bits up for the Flea .The switch that was on the flea was a Lucas 3 position so I didn't use the parts, but they fit nicely on the switch I managed to find.
The post that's missing is No1 looking at the diagram luckily it looks not to be in use so I'll just have to find the missing grub screws and a resistor .
Just had a look on evil bay and found a 1.5 ohm 20W ceramic tubular resister if that will do the job .
Hello Dave,
i modify a 3 positions for mine in that case you need also modify the center part to have the four positions, and you need have another "scrap"switch to ad another plot on the 3 positions, for cabling your it's not easy without a good reflexion, i could make you a drawing of what you need check in all the four positions.
on the workshop manual drawing the switche is in the position "only tail light" generator to tail light, and earth with resistance connexion, you need check with the 4 positions face in place, in all the positions.
maybe more simple to explain with a drawing , i make this this afternoon for you.
all the best
Arnaud
