Bendix mag problem on my '45 A-65

Need some of you experts to give me some advice. Last time I tried to fly, left mag was kaput. Didnt run on left at all. Not sure if its the switch or mag, but without an electrical system, how do you know? It worked fine the last time I flew, now nothing.
When I look at the mag it looks like it says Bendix SF4 RN-8, but info I've found here says my A65 should have the S4RN-21 (or -20 depending on Left or Right side).
Found the Bendix service manual on this sites link, but want to make sure its right since it is for the S4RN-20.
Maybe mine was replaced somewhere along the line...anyone familiar with these? How are they to work on, can you get parts?
