I annoyed people - I am having to ask for electrical help for tghe first time (I think). I spent all last night wiring in the fuel gauge/sender
(amongst other things). Now I assumed the following was how to wire it (Honda Blackbird) to the gauges:
Switched +ve goes to fuel sender +ve,
Fuel sender -ve goes to green wire (-ve) Koso gauges
I then set the resistance (tried 510 and 100 ohm) but alas I get nothing on the screen. Can anyone explain how the hell these things get wired in? I
hope this makes sense!
I just connected the koso fuel gauge wire, green I think, to the centre post of my sender then made sure my tank was earthed.
It reads something, not sure how accurate it is yet since Im not on the road so haven't filled it up yet.
So the KOSO is providing the +ve supply, that runs through the sender to earth? Ok, some rewiring tonight then...
Fuel guages are usually wired like this.
Ignition Positive ---- Fuel Guage ---- Sender ---- Earth.
If you wire it up as above, then take the wire off the sender and put it to earth at your tank, with the ignition on. The guage should read full.
Take it off again and it should read empty.
Also it's a good idea to make sure that the float goes through the full range within the tank. You can check this by removing it and moving the
float outside the tank. Holding it in the various positions, IE half way, quarter way etc. Don't forget to ensure you have an earth on the
cover.

if your using robinhood/lolocost sender which is sierra (i think,thats what im using) then on 100 ohm you can put about £10 in and read nothing where
510 ohm reads half full when empty(mk tank) so need to rectify this with a variable resistor(another winter project!)
Not sure about 2B tank but this is my only prob so far FWIW

Well it finally reads something. I think I will need to re-bend the float as it currently reads 6/10 when there is little more than 3 litres in the tank. B ut at least it now reads something! Thanks for the help chaps. Much appreciated.
