Coil ohms all over the place

[ebbrey]

So.. ive been fiddeling with my penelope for a while. Something that annoys me are the resistances and how its jumping back and forth.

I've made sure there is a good connection between the NR R NR wires. One end is around the post secured by the nut. The other end is tucked in the channel under the wick. I have also tried tucking it under the nut that locks against the base. I only use dead soft .999 NR wire and Kanthal A-1 30 and 32 AWG. I have been using doubble wick but lately moved down to only one wick. I wrap the coils tight around the wick.

What happends is that i make a coil. Lets say 1.2 that the latest one was. And i use it for a coupple of hours no problem. After this its suddenly on 2.5 ohms so i have to crank up the volts. 3 puffs later its a E1 error on the provari, checking ohms its back down to 1.X again. Lower the voltages use it for some time then suddenly no vapor production at all, check ohms. 2.3 2.5 2.9.

How are you guys handeling this?

My ohms typically will stay within .1 or .2 of there original reading. Something sounds off as you already know. Wish I had an answer. Someone will though I'm sure.

its a connection issue for sure ebb. Do you use 3mm fat wick or 3,5mm? And if you keep the negative NR wire under the locking nut (as you said that you did) the same happens?

i heard of this issue in some review, im no expert here but the guy said he didnt tight the wire enough and that fixed the problem.

I use 3mm. And yeah i have tried with the NR wire tucked in channel and pulled it out between the base and the rebuildable part to lock it under the nut that the flow control closes on to. I will try and build a new one again and see if im too cheap around the center post.

Couple things to try.

1 Make sure the wires are not sticking up high over the wick or poking out the side much of the channel where wick bends down into the side slots. If they are they could be coming into contact with the mouthpiece when you adjust the juice controll whick will cause either a short or ohm fluxuation.

2 Try the neg wire under the locking nut.

3 Either be very careful with how you lay the wick in the top of the ceramic or try fewer coils. One thing I have had happen when I make a high number of coils is they will be perfectly spaced when the wick is completely straight but when I put the wick into the ceramic is curves slightly which can cause the bottom of the coils to come in contact with each other. I have even had an odd build where when the mouthpiece was off everything was ok but when I put the mouthpiece on just the pressure on the sides of the wick caused a curve which did the same thing.

1. Yeah ive been doing this wrong... I always have my "connectors" upwards. They prolly touch stuff they shouldnt. Thx for the tip!

2. Neg wire under the locking nut has made me belive its more consistent connectiion.

3. Im trying to have them even spaced out and i never do more than 3 or 4 coils. Dont want anything to touch. I think my problem is that even tho no coils touch eachother i think the connectors or "joints" might have touched the ceramic housing or the mouthpiece.

Thanks for your replies

Have you wrapped the negative wire around the leg of the wick in the channel? This helps a lot with keeping contact.

Nah, havent tried this.. I usually cut it a little longer than the channel then "roll it up" some to make more wire contact with the channel under the wick
