toasted the wideband?

[tmadmsp]

I installed a wideband in my car a little over a year ago, bought it off of ebay, worked good for about 3 months then flashed on and off a few times and went black never to work again. i have power through the wireing harness but nothing coming out of the gauge. im assuming it shorted out anyone else have anything like this happen? can i buy just a gauge from anywhere?

checked all your grounds?? The flashing on and off could have been the ground coming loose and reconnecting until it finallt came all the way loose.
