Replacing a Field Coil with a PM Speaker - Please Help
#6

Thanks Raleigh - That set me mostly straight on the wiring except for one wire. Without a field coil, what happens to the Green and White wire coming from the 8uF which used to go to the FC? It should be no longer needed...is this correct?
Could someone explain the basic flow of voltage from the rectifier to the filters running, then to the FC. I thought the DC voltage comes from the rectifier, gets filtered for smoothing by the 8uF filter to ground, then it feeds the FC...is this correct? How does the 4uF function if it does not connect to the rectifier at all (note: part 32 is not in my model, so I am assuming the 4uF line does not connect to the rectifier)? I think my lack of understanding of how this end functions is making me confused on the wiring. Thanks for the help guys!!
