Fuel gauge not working

[reggit]

The project bike I bought has a duff fuel gauge.  Thought I'd take a look whilst waiting for other bits to arrive. The green connector on the tank appears open circuit, guessing this should give a resistance?  Still waiting for workshop manual to arrive, so could someone let me know the resistance range so I can check the rest of the wiring/ gauge assembly?


Thanks

Details from the manual (but haven't personally checked my own sensor)
FULL = 4-10 ohms
EMPTY = 90- 100 ohms
Hope it helps !

That's great, thank you.  Looks like just the tank sensor faulty - phew!

Fixed!


Drained the stale fuel out of the tank and took the sender out - it started working, probably not for too long but saves a bit of money now!


I assume the fuel light is meant to be two stage - dim then bright?
