ODNO - Smoking Ballast
I have found more info here about ODNO than on reef related sites. I'm trying to outfit my 20gal high salt with ODNO. I bought a 2-40w T12 ballast to run 2 20w T12 bulbs. I wired as the diagram suggested but found that in order to be true ODNO, I would have to wire in series to get the desired result. I tried this last night but must have done something wrong. My ballast began smoking, I reconnected using the original wiring setup and it worked but am uncomfortable leaving it on. Have I ruined the ballast or should it be fine?
