wrong guage reading
Hooked up the fuel gauge through a 6 volt resistor as all the original gauges were 6 v. the rest of the car is 12v.
I got no signal... tested the wire going to the sending unit and the test light flashed. Switched the fuel guage to 12 v and guage is working but registering full, even though I have a measued 1/2 tank ( 12 gals in a 24 gal tank). Is there a rule of thumb about adding resistors to bring the guage and tank into sync?
