You can get a generic ignition at NAPA auto parts. I got one for my Big 40 there for about $20. I put a standard 12 volt automotive battery in my machine, but not exactly sure the CCA's. Get with Ksellon on the forum & she can tell you anything you may ever want to know about SA 200 machines. She's a wealth of knowledge & ready to help. :-) Good luck. S.W.
