I think you are misinterpreting what I am saying. I had both senders out and hooked up a multimeter to them to measure resistance. As I moved the float arm thru its range the resistance varied from 1 to 50 ohms. It didnt just stay at 50 ohms throughout. Like I said I measured the resistance at the contacts on top of the sender units with them removed from the tank.
Where would be the next point I could go in the car to check the wiring and what readings should I be looking for?
