I decided to pull my 60A alternator to have it bench tested because I've been having some voltage fluctuations between 12.5 and 13.9. Imagine my surprise when I pulled the boot back on the output terminal of the alternator and found the insulation around the ring terminal burnt and the wire badly corroded. Corroded enough to allow me to pull the wire from the terminal end.
Now I know why the voltage was wandering. I checked the other connections and this is the only one that was corroded.
I have 575 hrs on the airplane and this is the first problem with my electrical system. This original connection was only crimped, but the repair will be crimped and soldered.
