Dan, if you had one of those switchable resistor boxes (say 1 to a few hundred ohms) you could probably come up with the correct sender value. At low to near zero resistance the gauge should full needle deflect but then keep trying different higher resistance (perhaps 30 to 200) until it just barely deflects (i.e. on the other side). If the resistance is too high it wont move at all but the correct size (on the high end) will make it defelect just a little. Many simple senders are in the 0 to 30 or 0 to to 200 or so ohms range, so use a switchable box until you find the resistance range to make the needle swing side to side without overdriving it either way. NOTE this is for the older 2 wire gauges, some newer 3 wire gauges in order to draw less current had sort of like a center tapped ground with two internal resistors that nulled out

The British government still reeling from the effects of the war on the economy, approached the Nuffield organization to see if they would design and build an "ALL NEW" British built wheeled tractor, suitable for both British and world farming.
