Check all the internal settings, watts, etc. Take the coil out and reinstall, prime, reset internal settings to new coil, etc. Coil might not be installed right enough or maybe it burnt if not primed properly first time. Charger plugged in should tell you how full batteries are…fully charge for several hours. Ohms should be about .4 and volts should be 4-5 if it's the original pieces in the kit. 60 watt setting should be fine depending on juice. Coil should be fine well above this. Picked up mine last week and love it.
