Have you tried the new Drafts feature yet? I just lost a long message today and learned my lesson. It is a good idea to save a draft of any long post you are writing. You can then just keep writing and keep saving a draft, knowing you have a backup if there is a glitch. The draft is automatically deleted when you post the message.

Hi all does anyone know where i can get my hands on a Miller ignition/light switch for my Dragonfly, i have tried the LDMC with no luck any advice would be gratefully received.
or even if you know the correct Miller part number would be a help.
is there an alternative part i can use ie lucas.

Cheers Kevin.

Hi,
I'm in the same prediciment - did you get any replies re the Dragongfly ignition / lights switch?

eddie

Are you without a switch or just got a faulty one?

Miller switches sometimes give trouble if the contacts are not pressed hard enough against the centre drum. They can be dismantled and worked on. First, knock out the roll pin and remove the knob. Then on the underside, undo the two 4BA nuts between the terminals (on the Dragonfly, one holds an extra terminal). The top and bottom halves of the body can now be separated, revealing the 2 balls and springs that locate the drum in the various positions. The drum is retained in the bottom half by a split pin - with the split pin removed, the drum can be pushed out from between the sprung fingers. Any fingers that are not making good contact can be tweaked to increase their pressure. Take the opportunity to replace the balls and springs and grease everything well with 'Vaseline'.
  Initially, poor lubrication of the balls probably caused the switch to get strained as it was operated, resulting in deformation of the spring fingers and erratic contact with the drum.

  Hope this is of some help,
                                         Regards,
                                                       Eddie.

Hi Eddie,
Thanks for the info.
Mines missing, don't know about the other person.
Think mines a Lucas headlight switch, so probably will make up some sort of special two switch or multi switch arrangement for mine.
Thanks anyway, - never know may come across the correct one sometime!

Hi Everybody,
For a Douglas Dragonfly.
Anybody know of an alternative for the Miller ignition/light switch.
Or a method for changing the wiring circuit to suit available switches.
