hey guys
i'm having alittle problem with my reserve fuel light, it never turns off!
what is going on with my fuel float?
thanks for any help

Mine never works haha but is your fuel gauge working fine?
sometimes when fill up the tank, he marks empty...then suddenly it returns to working...
as far as I know, there is a separate device for fuel light, which embedded to fuel float.
or, there is another small float attached to fuel float.
that little float must be stuck, take them out of your fuel tank to inspect.
sometimes a little knock-knock at the fuel tank solve it.
Before changing the thermistor or complete sending unit you first need to check the system. Test the low fuel lamp by grounding the thermistor wire under the back seat with the key in ignition, (i think is a green/red wire) if the lamp lights up, the thermistor is bad, if not, the lamp is burnt or the wire is broken somewhere.
The sending unit in the fuel tank is in fact 2 devices, a float with a resistor attached, and a THERMISTOR (basically a resistor in a bullet-shaped case) for the low fuel light.
The working principle of a thermistor is temperature: When the fuel is high, the thermistor is submerged and is cold, having very high resistance (around 1500 ohms @ 25 celsius) so no current flow. When the fuel gets low enough, the thermister is not submerged in fuel and the temperature rises, so resistance drops, so current flows, so lamp lights up, so you go to the nearest gas station.
So many reasons why

Woot thanks for the info! I never bothered to check why its not working before haha.
life is funny someguys never seen the light on
and i always see mine on... at night that strong red light ,that haven't dim function, obfuscates me...
Welcome guys!

So I've decided to drop the tank and see whats up with my FUEL light not coming on even after I've drained the tank.
The thermistor broke into pieces ><
Does anybody know if a regular thermistor would work as a replacement?
Screw fixing the original sensor! I tried everything I could to replace the thermistor with stuffs that I have lying around and it still wouldn't work.
I've decided to built another circuit to work off the float level, turning on the lamp around < 8 liters left, just like how the stock system works.
No that circuit doesn't work -.-
It won't go off even when the tank is full. Well when I had the sensor shorted so the gauge would read full haaah!
Now back to finding another circuit that would work.
