They’re worthless anyway. 70 degree sweep from 18 to 8 volts tells you nothing. Though they probably get too many service calls if the range was a more usable 11 to 15.
They have told me many times when my alternate stopped charging, especially on cars with mechanic voltage regulators. Anything under 12 volts, your car won’t start. If your alternator is charging properly, you should be around 12, and around 13-14 volts when the engine is running. Higher than 15 you’re overcharging and need to fix something.

Same reason ford ditched the oil pressure gauge.

I agree with that. My point is that there’s no resolution on that gauge
