Hi everyone!  I'm new to this so please be patient with me.  Thanks in advance!  I have a SA 200 ~66 model.  I need the main armeture.  I meged the coil leads to ground but don't know what resistance I'm supose to get if any.  Also got a hold of a SAE 400JXD machine.  Are there any engine parts out there?  It's a 6 cylinder engine and I've never worked on them.  Not even sure what parts I need. Thanks again!
