New fuel sender stuck on full
I'm after a little advise.
I've just installed a new Wema S5 fuel sender (240-30 ohms) and connected the two wires up and the gauge reads full when I turn the ignition on.
So far I have disconnected the wires from the sender then touched the pink and black wires together with the ignition on and that reads full on the gauge, so I know it's not the gauge.
I then checked the resistance of the sender and it's reading 200 ohms (tank is about 1/4 full).
After routing though all my electrics, I have power going to the ignition post on the gauge, then pink on the sender post which goes down to the fuel sender, then a black wire on the ground post on the gauge going to a negitive bus (i think), also from that bus is another black wire which goes to the fuel sender too.
I've checked the resistance of each wire and only getting 0.002 so that rules out corrosion.
Is there anything I'm doing wrong?
