If there was a problem with your Arbiter or Wake Tank RTA shorting out your mod would display an error message. Most mods will.
I read the thread . . . seems to me that the ONLY thing you have not tried is another mod with your RTA's.
As I understand it, your RTA's were working fine until the electronics in your mod started with NOT displaying the number of puffs correctly.
You've been building RTA's for a while, so I am led to believe you have coiling and wicking down pat.
You have two RTA's that are doing the same thing on your mod. Known good RTA's are NOT going to be the cause of your mods puff counter wigging out.
Common sense tells me that the problem is likely with your mod.
If you are able . . . take the mod apart to see if there might be any juice that got onto the electronics. If any juice got into the mod clean it out with some alcohol, dry it sufficiently and then retry.
If it still doesn't work then your mod is likely hosed. Replace it.
Do you know someone with a working mod that you can try your RTA's on? If they work on another mod then you know your mod is at fault. Simple.
Good luck!!!
