Erratic Gauges

So i was able to check the voltage on the cluster in the car, but in the process I blew the fuel gauge by touching too many things at once... So I removed the cluster out of the car and started doing bench tests. From what I could tell I believe the issue was with the connections to the voltage regulator itself. I was able to get it to replicate the bouncing outside of the car, but after a couple changes out of the voltage regulators it stopped. So I have to get a new fuel gauge from my stash, and I ordered the solid state voltage regulator. I will hopefully no more after this coming weekend.
