fuel gauge

[Matchless]

Now you have me a bit confused when you say you checked for continuity and - nothing. Does this mean the light stays on when you remove the wire to the switch or is the light going out? Initially I understood that the fuel warning light stayed on once you connected up the wires and the tank was full. If it is not going off when disconnecting the wire on the tank switch then it is getting an earth from somewhere else.

Thread resurrection time!
I too want to replace the OEM fuel gauge on my 81 GS750E. Now then, since the sending unit is just a variable resistor, should it not be possible to make an LED gauge of sorts? Perhaps 5 LED's, one each for Full 3/4 1/2 1/4 & Empty?

I'm no EE but I can follow suggestions!

ggrenfield, yes. you need to have a voltage splitter circuit. i'm working on this myself, but ran short of money and have not actually wired mine up to see if it works. if you are interested in checking it out, though, i've got a thead about it, complete with schematics.

you WILL need to find out your resistance range, (mine was 10ohms empty, 130 full) so i didn't change the resistance in the schematic, but you will need too if it's much beyond that, otherwise it will be pretty innacurate.
