Voltage gauge inaccurate for anyone else?

[hgeranium]

I’m pretty sure this is a common thing but was just wondering if there were any  possible fixes. 

 

With a multimeter, I’m getting 14.3 V at idle with no accessories and with AC and lights on, it’s at 14.1. While the gauge reads ~13.8v and ~12v respectively.

 

It’s just annoying never being able to trust it, especially if my alternator were to start going out, which has happened before.

Probably a bad ground somewhere.

 

Try this.

Usually is a bad ground and power wires. I cleaned the hell out of all of mine and I get accurate reading at my voltage gauge.

Thank yall so much! I feel like that should’ve been the first thing I checked lol. The fix seems simple enough.
