64 valiant gauge problems

Too bad you couldn't have swung the arm manually while someone watched the gage, or tested both on the bench as I did. Anyway, 70 ohm = empty is close to factory spec, and 10 ohm = full as I recall. I added tweak resistors to the back of my circuit board to make it perfect, plus adjusted the voltage on my new electronic limiter (while not screwing up my temp gage readings). The new sender was a bit erratic until I popped of the cover and bent the wiper arm so it was tighter.

One guy here (Kit Carlson?) was considering selling an in-line box which would let you tweak the fuel readings perfect, and work on any U.S. car.
