Just to complete the total confusion: If Y=Resistance needed for full
reading and its a parallel circuit:
1
R1= --------------
(1/Y) - (1/R2)

Subject: Gas Gauge Oddities
I'm trying to get my fuel gauge to work properly. Before, it would
always read 1/4 tank if the level was > 1/2 in the tank, and read
properly below that (although sometimes it would read 3/8)
I've got a new(er) tank sending unit from a TR6. Now, (just by putting
the sender into the circuit and holding the float at its limits) I get
correct readings for Empty but Full puts the needle pointer at just
below half.
Any suggestions? When I pull the sender out of the circuit and short
the leads (~0 resistance), it reads just under 3/4 tank. So either
something's too resistive or something's not getting enough power.
Where do I start?
Thanks in advance...
