Hi Robert;
Congratulations on getting a new-to-you Saratoga SP.
I am the owner of a 180 Comanche and I have been able to get all the parts I have needed over the past 15 years. Of course, the supply chain, shortages and increased cost of everything including shipping has extended lead times on many items.
A few years ago I did need new engine control assemblies. I was able to get new ones made to the specifications of the old ones by McFarlane Aviation in Kansas. McFarlane has FAA approval to manufacture a wide variety of commonly needed Piper and Cessna parts.
I finally decided to give up on my old 50 amp generator-I’m an A & P and it’s my personal airplane so I had the time and tools to repair and refurbish it as needed–and replace it with a FAA approved 70 amp 12 volt alternator and regulator from Plane Power.
I suggest you take a little time to go the the Piper aircraft Technical Publications page (https://www.piper.com/technical-publications/) and select your airplane in the drop down menu on the left-then you’ll have a list of the known problems (and factory fixes) with your airplane.
Let me know if you need more help.
Steve
