I am sorry, but I can not tell you that information - I did not keep track! I do know that I over-wound it, though, and the part of the flywheel that will hit is not the outside, as you might expect. It is the small hub section, with the key way cut in it that will contact the coils first. I had to remove at least 1 full layer, and re-solder the end.pumpguy wrote:Can you tell us the length of wire and the number of turns you used?
I started off with a 300' spool of 18 ga, and I did not even use half of it. I think that I was only able to fit 3 full layers on the core. I was as neat as I could be, but I was in a hurry, so the last bit or traverse did not lay as nicely as I would have liked. When I was done, it worked very well - so I am led to believe that the whole process is not very critical, as long as you are not super sloppy when you start wrapping. I believe that you could even wrap it in a dumbell shape, and leave clearance in the middle - to clear the flywheel hub - and it would still work just fine, maybe even better. My hands were sore when I was done. I just clamped a screwdriver in a vise, and speared the arbor hole of the spool to pay it off. Then I just tensioned the wire with my hand (wrapped the wire around my fingers?) as I wrapped it on.
I am very happy with the results, but the real test will be when I try a 55/60 watt headlight. Right now, I have one of those 35/35 watt "Blue" bulbs from Rocky Mountain ATV. It works pretty good as is, but for actual night time street use, I really want a 55/60 bulb.
