Low Fuel Warning Light
Low Fuel Warning Light
I have seen a lot of complaints and responses to this subject. I have tried every tip that I have seen, except replacing the Fuel Reserve Sensor. The light itself on the cluster gauge is soldiered it to the circuit board, so no replacing that. I don't have a blown fuse. I'm sure someone will say, replace the Fuel Reserve Sensor, which I plan on doing. But if that doesn't work, I have to have a plan B. Yes, I could watch my mileage, which I have been doing, but if ya out riding hard, you may not remember to look at trip counter, the light would surely grab the attention. This seems to be a problem that a lot of people are having, does any one have a clear solution to this?

Just so thread responders know the rest of the story... Here's your other post from this thread - https://cbrforum.com/forum/cbr-600f4...2/#post1115592
Ha, my warning light doesn't work. I've crossed the brown wire to the ground, no light. I've connected the two wires, and I see the circuit is active but warning light don't work. I've plugged both wires to the fuel reserve sensor half way and tested the connections, test light proved good. Taken the cluster gauge apart and it don't look like you can replace the bulb, it looks like its integrated in the circuit board (go here to view a picture of it). I am a total lost as to how to fix this problem.

if the bulb is not working, you can wire in an external led light or replace the cluster. i would think that someone that repairs circuit boards could replace it. (i'm sure some of us old guys remember those circuit kits they sold at toy stores. those were the days.)
if the sensor is bad, replace it.
if you don't fix it, then you're stuck watching your mileage.

I removed and installed a new Low Fuel Sensor on my bike today. My low fuel light was not working on my dash board, so I had Cycles R Us (Used Motorcycle Parts Salvage Yard) order me a new Low Fuel Sensor. It only took about 20 mins to do, mostly the time went into taking off the gas tank and putting it back on.
The only problem I ran into was the fuel lines were old and the one to the fuel filter (about 3 inches long), sprung a leak very easily. The quick fix was for me to cut 3 inches off the over flow line. I will be replacing all the fuel lines next winter. I imagine that they are the original lines and are in need of replacing.

Glad it worked out for you.
Re: fuel line(s)... Yep, I've recommend the close inspection & replacement to many new members w/ older bikes. Those lines do get brittle & crack easily, causing leaks. Most bike shops keep rolls of dif diameter line on the shelf. You can buy by the foot & save money vs buying the length specific factory pieces.
