Help please, no power unless plugged in

[Smoove0214]

My opus 200 started saying ohms too high. I've been using the pre-built ni200 Crown coils with no problems.. I put a new coil in the base, that's when I noticed the mod had nothing on the display. If I plug it up to the usb charger the display comes on.. As soon as I unplug it, it cuts off again? Please help **I put my Arctic Tank with kanthal coils on the Opus and it's saying the same thing.. Ohms too high.. I just updated the firmware last night.. Haven't had any problems up till now..

Have u checked ur fuse to see if it looks blown? Opus has been having a lot of this going on .Check your ground and 510 connections...check your battery and balance connector

What is the battery reading?  What is each cell showing in device monitor?

I am having the same problem with a VapeCige VTbox200 which is the white V2 model.

It worked great for about 3 weeks, then died in the identical way as Smoove0214's.    It will not come on unless plugged into USB, and it reports "Ohms too high" when I fire it (also while plugged in, it does not fire when disconnected).  

* I have checked the Fuse visually and with an Ohm reader.  It looked ok (24ish, which I think is correct).  
* The Device monitor shows all three cells as good, voltage at 3.83 each, 11.49 overall.

Any help would be great.
