I've had a Zlide in rotation for about a week.  Last night, I got  'no coil detected' on Solo mod.  I cleaned the 510 connector with alcohol and reseated the coil.  No fixy.  I put the Zlide on two clean Picos, Asmodus Colossal & Vaporesso Gen S - no coil detected on any of those.  I assumed the coil must be spent so before pitching it I attached the Zlide to an old Clover Overlord pen style battery and it fires. 
 
I looked at Innokin Zlide trouble shooting vid

and read
How to Fix 'No Atomizer' or 'Check Atomizer' for vapers
After doing all this I remembered I put that Zlide tank aside a couple months ago for the same reason - I started getting 'no coil detected'.  No warning, just bam - it quits working.
Am I overlooking something obvious?  Here's a pic of all mods I tested with & Zlide is connected to the Overlord which does fire but, of course, it's not a great hit.
