So much time and money wasted fooling with batteries and starters, when a few minutes doing simple voltage drop tests would reveal the culprit instantly. This messing around for days is way too typical, and it's the result of not understanding the systems.

Go to https://skytec.aero/aircraft-starter-performance-issues/ for details. Stop messing with stuff and do this instead.
NO. Do it in the order shown. Saves time. Read the details in the website.
Voltage DROP measurements are what we use to find the tiny resistances that cause starter problems. As little as 1/20th of an ohm can cause a huge drop at the starter. Most ohmmeters will never spot that.
Absolutely!
It seems that over the past few decades, the prevalence of digital engine management systems has led to a mechanic's culture of throwing new parts at a problem instead of doing a proper diagnostic and solving the problem. That's easy for the mechanic and service shop, but expensive and time-consuming for the customer.
If you don't know what the problem was in the first place, how do you know whether or not you have fixed it?
