Hcigar kayfun lite plus not firing on provari

[fog80]

I just got a hcigar kayfun lite plus and for some reason it won't fire on my provari. I keep getting an "open" error. I've rebuilt multiple times with no luck. Looked at the 510 screw and I don't think it's adjustable.

screw in my hcigar kayfun 3.1 and it works right away.

I don't have either, but I would suggest to compare the pin length between the kfl+ and 3.1 to see if there's a difference, and then go from there.

What Ω are you building

If it is the pin length, go to madvapes and buy a couple of circuit board spacers. They will allow you to use it.

I have a Kayfun Lite Plus from EH and it works. Odd.

I build a washer out of 4 thicknesses of scotch tape. Problem solved.

 

[MilitantParasite]

Punch a hole in the tape, insert screw, and trim the edges with a razor blade. It will be enough to lengthen the central pin screw.

Coil is only 2.0 ohms. Looks like the length of the center screw is the culprit.

It's not the screw. It's the length of the center post insulator. Adding a gasket to the screw will cause the screw head to protrude out more and will contact the terminal. You may switch out the insulator but the new one may not be any better. Try to save the insulator because they're hard to come by. I thought of using some thick bit of upholstery thread looped in an overhand knot under the screw head as a gasket. It may be easier than making a gasket out of scotch tape.

Had the same problem with my wifes EHpro light +
My HCigar is adjustable. Kinda handy!

I made a very thin washer from sheet brass and put it under the center pin screw head. Works just fine now.
You can find this sheet stock at any RC hobby shop.

Although most Kayfuns are not adjustable, the HCigar 3.1 is. I would have thought that the Light version would be as well. Have you tried it? It usually takes very-very little adjustment to make it work!

Try putting one or two of the tiny orings on the center post screw. This worked on my Kayfun Lite Plus.
