Need to see a parts break down for an American MJB mag. Also for a Case mag. Not sure of the model Would fit an SC tractor.The Case mag the mechanism locks in but won't click. It turns but never clicks past to spark.Always has tension on it. Kind of afraid to pull apart with tension there. Never had one apart before.The MJB is off of the SC I picked up recently.No spark there.
 
I was fortunate to receive a copy of OLD ABE NEWS. FALL of 2000. In this issue there very well may be the information you need to have a better understanding of Mags made by Case. An issue , if available from OAN can be had from Bob Johnston 810-750-0529 or [email protected] Let me know how you make out. Best of luck.CM
 
Take a 13/16s socket and adapter and put it in your drill and turn the mag from the front end. All the impulse coupler does is speed the mag up to fire. The drill gives enough speed to give a 1/2" spark if the mag is operational. They will fire with no impulse coupler on the mag.
 
Chuck, I found my copy of Old Abe Fall of 2000 and read the article. Very helpful. Problem is the part that needs attention is the impulse unit. And they say it takes special tools and know how to do it. Best I leave it alone and seek help. Guess it will go to the shop. Fortunately there is one within 35 miles at Shiloh,Ohio.
