Very common in the electrical engineering world but sadly lacking in the small airplane service world. Just a few seconds monitoring the buss voltage would tell you if you have a diode problem or not. https://www.amazon.com/Siglent-SHS810-Oscilloscope-2-Channel-Multimeter/dp/B00GQNNSEK/ref=sr_1_9?crid=2WXKPIPQLL9BK&dchild=1&keywords=siglent+oscilloscope&qid=1615183694&sprefix=siglent+o%2Caps%2C236&sr=8-9 That's more than a new Alternator haha. I did find out the Alternator is warrantied for another 2 years or 800+ hours. Maybe it was a fluke and won't happen again. Quote

There are many inexpensive options these days if you only need to do basic stuff:https://www.amazon.com/Hantek-Oscilloscope-Channels-Handheld-Portable/dp/0201336421 https://www.amazon.com/Hantek-Oscilloscope-Generator-Multimeter-Multifunction/dp/B08PY84TQ6 Quote
