Ok guys. I've got her reading at 1.2ohms on my mech using multimeter and I'm pretty sure I have gotten rid of all the hotspots.
I have eliminated the really bright areas by nudging the wire and now all the coils are glowing evenly. I think I'm ready lol
--Edit--
Another failure lol.
I didn't realise that while nudging the wire, the top has actually come out of the screw/washer thingy on the positive post. I didnt realise it was loose until after i filled the tank up.
So I go to secure the wire again, instant hotspot

I'm gonna sleep on it and give it another try tomorrow morning. On the bright side, I mixed up a batch of 50/50% PG/VG
juice. I figure it should be nicely steeped by the time i get this blasted thing working lol.
I have noticed that the wire comes out of the positive terminal quite easily on the RSST, any tips?
