After installing my new Tanin dash, a low voltage light came on. I hadn't gotten a new battery since the car was bought, so....fair enough, bought a new Duralast battery for $130.

Low voltage light still on.

The battery leads are very good too, so that isn't it. Any clues? I don't imagine there's some massive draw, considering I've only removed systems, not added any.

 

There's a low voltage light that comes on?

 

Yes, red light in the bottom right of the dash. It's currently permanently lit with key on. 😊


Surprisingly, also, three of my backlight LEDs have failed. Tanin's generous lifetime warranty will hopefully only be used once...

 

The battery light is on with engine on or just key on?

How is your alternator? Our cars have a rep of having bad battery grounds.

 

Both KOEO and KOER. I imagine the alternator is fine, I've had no drivability/losing battery issues.

I'll search up those grounds.
