The cluster is out, you won't believe what I found

Hi dart273

So I want to be sure I am ok: down and dirty test on the Gas gauge.
take 2 D batteries, link them to gether, take 1 wire from + on battery and connect to 1 terminal on the gauge, then take another wire attach to - on battery and touch 2nd terminal on gauge. And the gauge should do something, right?
let me know, excited to see it move.
