Sedan sender
Wiring
There is a single Yellow wire on the sender. It goes forward to the dash Fuel Gauge. The sender is grounded through the tank body.
See main article: Fuel Gauge Wiring
Specifications
As measured by club members, by moving the float up and down from stop to stop:
- 12 ohms fully up
- 88 ohms fully down
- 35 ohms half full (per Nissan Factory Service Manual)
NOTE: This does not necessarily match "Full" and "Empty" marks of the fuel gauge, due to normal manufacturing tolerances. Typically a 1200 reads well 'E' before it runs out of fuel, this is normal.
