I think I fixed it. The voltage stabilizer was touching metal. It sounds weird, but it's not mounted behind the dash to a solid point and whenever it touched a piece of metal the gauge would drop. like the body of it was grounding out. I wrapped it in tape and tie wrapped it now it's all good.

Edit...I thought it was good. It's doesn't jump around, but I think it's not the correct level. Like I mentioned it has almost the same voltage on both terminals. I want to make sure this is the right part before I change it out. I'm not getting my 10V on either side for sure.
