ive watched videos of how to do the coil a munch of times and just want to make sure im doing it correctly, i have a fan thats has 2 wires on the one post, do i just clip one of them, unwind it half a turn so its now just long enough to reach the 4th post?

Yes just cut one wire and attach it to the fourth post. Trial and error is the method I use to find the polarity.

thanks for all the help mbrown, youve answered so many questions on this forum its nice to see that, i've just got all my parts in and im close to getting it.....im still learning all this stuff though, i do not have a second battery connected yet and was wondering if i needed it to get the fan to continue spinning as its only going for about 4 seconds, theres definitly some magnetics going on though.... 110vac light will blink quickly when i connect power, is there a way to tell if the vac light is backwards? will fan still work if its vac is connected backwards? i could possibly have used the wrong wire for the 4th post also, just trying to pick at some smarter brains here , thanks again

The second battery is there to collect the radiant energy, you could use a capacitor instead but the fan will run without it. Just be carefull to have the meon bulb on the device when a battery or capacitor is not connected, otherwise the transistor will get fried.

What is the 110v ac light and where are you connecting it? Is it the neon bulb? If it is then it does not matter about polarity as neons have no polarity.

its a neon..... i switched it around and its lighting up the same, just when i connect and remove power..... i just noticed my negative coils on my fan are getting super hot when im trying to get it to spin, could this be a sign of using the wrong wire to the 4th post?( i ordered multimeter a couple weeks ago but it hasnt came yet...)

remember you need to spin it by hand to make the fan run but check the polarity of the wires, you may have them the wrong way round, I do that all the time :lol:

I think my coil must be wrong, i might have even burnt out my neon bulb.... got a meter intoday, checking for resistance, is there a proper way to do this? ive just been checking posts on coils next to eachother, i got about 25 on two, and two with nothing, is there going to be one post that wont give a reading or should i be getting 20-60 between all posts? thanks again im new to all of this and have just started learning about it in the last 2 weeks

i just got a brand new fan! and as for the coil, i cut one wire and put it from the 3rd to 4th post and was getting 25 ohms between 1st and 3rd post, nothing between the others, am i supposed to be getting an ohm reading between the 2nd and 4th post too? i then swapped the wires between the 3rd and 4th post and was getting nothing between any of the posts so i went back to wires i switched originally, i may be at a standstill until i can get some more advice
