⚡ LIN bus alternators, explained — and why a 12.6V reading at idle usually isn't a problem. 📖 https://www.mechman.com/lin-bus-alternator-guide

Modern Ford™, GM™, and RAM™ trucks use LIN-controlled charging — your vehicle's computer commands the voltage, not the alternator. A healthy system can run anywhere from ~12.3V to over 15V, completely on purpose.

Before you condemn a "weak" alternator or chase a charging gremlin, here's what's actually normal — and what to check first:

✅ Why charging voltage changes with driving mode
✅ The "14.4V all the time" myth, busted
✅ What really happens when you go high-output
✅ How to diagnose a LIN system the right way

Mechman® builds high-output alternators that work WITH your truck's charging system — not against it.
