Well, I can't figure out why the range of the needle is so much less. It moves, but not as far as the full sweep as intended.
Is that a voltage issue?
I put a new sender unit 0-30ohm from the local auto part store.
It was difficult to get the gauge to work at all. I had to insulate it from the panel as it was originally. So do I need a voltage reducer after all? Or is it something different?
