I just got a bonzai halo inductor but im not sure exactly how u install it.
The stock inductor had 4 prongs soldered but the halo only has two prongs which way do i put it in?
It's a v847 replica
If you look at your stock inductor, two of the pins are common to eachother. In other words, there's really only two pins, electronically speaking. Just install your new halo inductor so that each pin is connected to the components on the PCB. In other words, don't put it in so that both pins are on the same track of the PCB.
