Gauge Cluster Issues/IVR

RedFish said
The limiter is chassis grounded via a slither of metal on the back of the gauge against a unpainted spot in the housing. test different ways on the fuel gauge. you should find the 20 ohm gauge, a 50 ohm limiter and a combined 70 ohms.

I [now] understand this grounding contact.

The brass sheet retained in the tabs touches what looks like gray. Do I need to look more closely at that?

edit: fixed! Thanks Mike69cuda!
