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!
