My coil is 1.4 ohms. I've only put about 6ml through it so far. I have the new sub ohm kit that came with the unit. Should I still clean the contacts after every bottle? With ISO alcohol? The firing pin and spring still looks like when the day I received it. Its working great again but just trying to learn for next time when it happens.
At that resistance you should not have an excess of build up on your firing pin or battery positive terminal.
I have been hearing many REOnauts talk about their battery shifting and causing their vape experience to suffer because of it. i have not had this happen to any of my REOs so I don't have a definite solution for you, but have a couple of suggestions that could be of use. First suggestion is to insert your battery as normal and vape without the door on. Then to install the door and see if it actually affects your vape quality. If you isolate the door as the issue remove the door, re-center the battery position but this time install the door from the top and slide it down so that the magnets on the door do not tug on the battery (these magnets are pretty strong!)
Ultimately the magnet can be removed using either the acetone method for untreated REO doors or it has been suggested to apply the tip of a soldering iron to the magnet allowing it to heat up and the adhesive releasing the magnet when attracted to another metal object (say like a nice beefy flat tip screwdriver). Make sure if you are using the soldering iron to not apply too much heat that it damages the doors finish on the opposing side and also both the iron and the door/magnet will be hot!!
If the door isnt the issue I would grab a multimeter if you have access to one and we can proceed from there.
