Alright, here is my newest issue. After my wideband install, it came to my attention that my car has some voltage issues. With headlights and a\c cranking at 4, my voltage falls on it's ass to 11.7 ish, and the wideband throws error codes telling me it's unhappy. Without the a\c, it's a healthy 13.5 +.

So my situation is this; has the problem been there all this time, and I was unaware because I didn't have the wideband, or is something else the culprit.

I know for a fact that it isn't the alternator.

My callout to all fellow wrx owners - What are your voltages under similar situations. I'm looking for real measurments, no speculations please. I appreciate any data anyone can give me.

Thanks

later, x

High 13s to low 14s thanks to an HKS grounding kit.
