Default Atlanta People, Need Help!

My AEM UEGO gauge was working great, then a couple of weeks ago, it started showing readings all over the place, and then sometimes it would be ok. After searching, I read that this is a symptom of poor grounding. After checking, all the connections were fine.
Now the gauge won't even power on, although it's getting solid power and ground at the harness at the back of the gauge.
This may sound dumb to some, but I'm wondering if anyone locally would let me come and try your AEM wbo2 gauge in place of mine and see if it works properly, just so I don't buy the ~$200 replacement gauge and find out that there is a problem elsewhere (although it's not likely). Kind of a peace of mind thing.

Don't have one - but I was going to say ground. Readings all over the place is a sure sign of a bad ground. Is it sharing a ground with any other gauges? Or even the grounding point? If so, I'd isolate it.

Nope. It has it's own ground.
However, after further investigation of the underside of my car this evening because of a speed based noise, I can really only conclude that when I was run off the road a while back, the sensor harness running back to the only usable bung I have right now (in the FM exhaust, right after the test pipe) was somehow snagged loose of the heavy duty zip ties that held it against the PPF. From there, it battled the driveshaft knuckle and lost miserably. Thus the noise and the very much dead AEM WBo2.
So nevermind, time to find a new wideband.
