Lighting coil #402-4240. (60 watt)

Would anyone out there happen to have an old 60W lighting coil in their parts collection? Mine is bad, and going to rewind it myself, but need to know what size the coil winding wire is. If anyone happens to have one handy, and an accurate caliper, I would appreciate if you could measure the diameter of the winding wire, in a fractional inch or mm measurement. Thanks! (Ps.. in the final stages of getting it on the snow. Found a brand new NOS Dayton belt for it in Ontario that is enroute to me now. Axles and bogies rebuilt, 399 is running good, lighting is not a major issue for now, just want to be able to tear down/rewind in the same day I attack it.)

Getting excited to get this thing out and about for the first time. Last registered in 1988. Been sitting since that time.

That's great that you are in the home stretch now - bring it home! You will have to show the sled on here once its ready to go.
If you aren't opposed, it might be easier to find an intact coil so you don't have to rewind one. Ask 775 on here, or Goose or ebay to see if you can locate one. There are others as well - maybe someone has one in their stash? Rewinding one is pretty neat though if you can pull it off. Do you know how many windings you'd need based on the output you want?

Hi Olyman, oh yeah, I will be posting some photos when she hits the powder. Will be waiting to do some painting (the black, and yellow skis) next summer. If I can find a coil from someone, I'll give that a try first. Will still rewind the existing one, as a spare if that happens. I don't know about the windings count; will have to unwind it carefully and count turns. Looking at the electrical drawings, it appears schematically, that the coil on the pull start is only using half of the winding. There is a center tap point on the windings, and the headlight pulls from center tap to one end. In the drawings, for electric start units, it shows both ends of the coil going out to a rectifier. So I am curious to find out if that is true. Maybe its just the way they made the drawing, but if you believe the drawing, there should be another half of the coil on pull start units that isn't used. Will provide updates later on, when I get to that point.
