Please Help

my opus 200 is acting up.. It started saying ohms too high, I've been using the pre-built 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, but if I plug it up to the usb charger the display comes on.. As soon as I unplug it, or cuts off again? Please help **I put my Arctic Tank on the Opus without the tc on, 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..

Check your fuse to see if it looks blown. ..check your ground and 510 connection. ...check your battery and balance connector
