Okay, so I have this Wico X Mag that has been sitting on the shelf for awhile. Came off of a JD I scrapped, but of course, I clung onto a bunch of this kind of stuff. It never did turn, the shaft that the rotor was on would NOT turn at all.
So, I now need a mag for my B, so I started messing with this one yesterday. I took all of the stuff off of the back, and then took the 4 screws out. THEN I took the cap off, then the rotor and stuff, and then proceeded to LIGHTLY tap on that shaft, and it easily tapped out.
I then discovered that the reason it wasn't turning, was just due to the hug amount of rust and corrosion around the area that those magnets turn inside the housing. So I cleaned up the shaft, magnets, and all that stuff.
Then I decided to try to clean out the housing. It didn't want to clean up with standard methods, so I decided to just barely hone it out, that worked very well. Didn't take any metal off, but made it look MUCH better!
Greased the shaft (with just a little engine assembly grease) and then slid it back in. Now it turns freely.
Then I put it ALL back together, re wound the spring on the drive and everything. But I still don't have spark?
Then went and cleaned the points, they were pretty bad, and also cleaned that spring/contact that touches that big cluster thing, also cleaned the clusters contact.
Still no spark. Should I be able to get spark by turning that thing by hand, or does it need to be grounded out on the tractor?
Any help would be appreciated! I am NOT about to spend $400 on a "rebuilt" mag, so I need to figure out how to fix my own! :)
