OK, I've searched and found a lot of discussion on this. I have a DPDT on hand On-On-On and a Digikey 4DPT switch. I'd llike to wire Series / Parallel / Outer coils. I think the 4DPT is almost like having 2 mini-switches in one and is probobly the one I need to use but I'm not sure how to wire. I have a pair of Bart MK4's I'm installing in my Lakland 4401 A solid wiring diagram would be much appreciated. Thanks ahead of time.
