fuel light thermistor

[eddydog]

Hi. Tell me, please, value of thermistor resistance of fuel level indicator. I did its job 4 year before, but not remember now, I have about 200-300 Om, but fuel indicator light. Tryed 1 kOm same. Maybe need more? Thanks

Does anybody know which part thermistor should be used, please?

I have problem with no reserve light on dashboard. I have opened the tank and there is a small sensor (thermistor?), just two wires. When I connect them with piece of wire, dashboard light lights up. So problem is that sensor.
I have also found that some guys repaired this problem with 1k NTC thermistor. So I installed new thermistor, but.... it didn't help. Or is problem, that no current flows until engine is running? I have checked this only with key turned on, but not engine started

Old thermistor showed around 2,1k OHM...
Can anybody help?

Thank you very much

I did some testing today. Made a small circuit which included only batery, thermistor and light bulb. After everything connected together it took a little while but bulb started to shine. After puting thermistor to petrol it stopped the shine.
Problem is, that I don't know what current flows thru termistor when key is on and if it rise after engine starts.
Does anybody know, if the reserve fuel light turns on even without engine started, please?

From memory with my old Corsaro, the fuel level indicator is a simple float, so if the sensor is low the light comes on pre-start once the ignition key is turned. I'm no technical person, but the way the reserve light worked it always seemed as if it was operated by a bobbin in the tank, being lean and slope dependant. The modern Chinese ones act the same way...

Good riding,
