inconsistent heating on dual coil set up

[fizhak]

I recently purchased a vanilla copper mod with a tugboat rda. Both authentic. First build was great. I recently rebuilt it and one coil was really heating up. The other not so much. I clean my mod once a week. Not including the rda. Any advice on how to fix it? Thank you.

Make sure all connections are clean and coils are the same and both secured good.

When your coils heat up at different rates, they do not have the same resistance, which means one wire is longer than the other. Make sure the legs on the coil are the same distance from the posts and the coils have the same number of wraps. Takes some tinkering, but you'll get it right.

PS: Wolfenstark has a good point about the connections being secured. Sometimes after tightening the screws down, one of them can loosen a little bit. Double check them.

Make sure your screws are all tight, lengths are all about the same, spacing is all the same, and just heat and tweak until you get it to where your happy.

I see good advice above, but I'd also recommend you squeeze the wrapped part of the coils together a bit (gently). This has done the trick for me numerous times in the past. Just keep tinkering with them; you'll get there.

Everything everyone else has already said but also before you wick you should pulse and compress the coils it makes a world of difference

Agreed squeeze coils and tighten screws, has solved the problem for me more then once

you can also try the strum approach after the coils look good - just take your tweezers or standard screwdriver (as apposed to philips) and run it across the top of the coil. the goal is to "disturb" the coils a bit, but you dont want to jack them up - just provide enough pressure do cause them to "vibrate" a bit - with kanthal they should just bounce right back to being tight. no need for the coils to be hot when you do this... infact that may mess them up..

Thank you for re info. I ended up cleaning the screws and that did the trick. Is there a way to clean the inside of the posts or is that not an issue. Also, with regards to the strum approach, is the goal to bend the coils a bit or just scratch them?

just get them to vibrate a bit - you dont want them to bend at all.. visually, the coil should be unchanged.

That makes sense. I will give it a try the next time I change the coil.
