coil not detected on aegis legend

[MikeSolver]

I've tried known good attys I have that work fine on all my other mods,I have removed the 510 plate on the mod,visually watched the pin receed down as I installed the attys, I ohmed out the main ground, positive and negative coming out of the 510 ,it's ok. Anybody have any suggestions? Besides a $90 paperweight.geek vape have a fix?I also reset the mod and firmware is updated.tried different batteries also.
Thanks in advance. I will check it at the https://myecigs.uk
