Re: converting a 90ohm sender to a 30ohm sender
I may have interpreted Docvette incorrectly but I think he was going from 30 ohm to 90 ohm and not 90 ohm to 30 ohm. The formula for resistors in series is R=R1+R2 so any resistance placed in series is added to the 90 ohm. But resistors in parallel is R= R1x R2 / R1+R2 so 90 x 47 / 90 + 47 = ~30.87 ohm, but it wont be lineal because at 1/2 tank @ 45 ohm parallel with 47 ohm you get ~23 ohm which is about 3/4 tank on the 30 ohm system.
