The "Low Fuel" light on my 1500 works, but when it comes on it is so dim it can hardly be seen. So I breadboarded up a circuit to detect this and light the bulb brightly.

I determined the Low Fuel bulb only sees about 5 volts or so when it comes on...

I can draw up and post the comparator circuit if anyone is interested.....
Hi Denverwinger:
Let me say I’m not a tech, just hobby fan and still learning, everything is achieved by trial and error.
In my case the low fuel sensor has had burned several years ago, so I tried the Virgilmovil method but couldn’t find a reliable float, they either deteriorate or sink.
Last year and using similar elements I reached a different approach.
I started with the LM339 and did some bench test; in order to shrink the unit in perforated board I used a LM358, 1.3k ohm Thermistor, 2 voltage divider for the comparison circuit, and output tied to the base of a 13003 NPN transistor (from my salvage box) grounding the LFL.
Build a test bench jig that raises and sinks a thermistor in gas every minute, and for 3 days it worked Ok. To prevent a short or fire encased the thing in epoxy and fitted in junction by the gas tank. Left about 1 ½ gallon in it, and went for a ride around town; surely enough in a little while the LFL came on, replenish with more gas and again work Ok. So I fill it up.
Went for a longer ride and after some 30 minutes….Surprise!! .. LFL is ON!! And it wont dim.
I think that since I ran bench test out of a 12.4V battery while bike is running the voltage goes a steady 13.9 V, that difference did upset the voltage divider enough to generate malfunction.
Right now I’m putting an aux input to the radio, next will go back to FLS, have pleny of time.
Perhaps you (you seems to be more tech than me) or someone else can give me a clue of what’s the problem.

Hi Mario,

Here's the circuit I came up with...

Disconnect low fuel light at the sensor and insert this circuit, Also needs AUX power from the fusebox.
Comparator is LM 339 (4 comparators in one package, unused inputs grounded). Transistor I used is TIP42 'cause that's what I had handy, any garden-variety PNP will work if rated 20v or more, collector current 500mA or more. Most TO-92 pkg transistors won't handle the current. #194 Low Fuel bulb pulls around 300ma at 15v and has surge current when first energized.

LM339 is open collector output, simply floats when not triggered. 1K resistor really not needed but is pull-up from base of transistor. LM339 output goes to ground when triggered, causing PNP transistor to conduct, providing ground path for Low Fuel Light in dash.

The 5K and 15K resistors are the voltage divider providing 3/4 of the system voltage as a reference to the inverting input of the comparator. Nominally 8v assuming 12v power.

The sense input is tied to the junction of another #194 bulb connected to AUX power and the thermister in the tank. If Tank is full and thermister is cold, resistance is high and sense input will see around 11-11.5v nominally. So comparator is off. But if fuel is low, resistance of thermister decreases and lights the second #194 bulb dimly, voltage at the junction with the thermister drops to around 6-7 volts nominally which is less than the reference voltage, tripping the comparator.

I added the 10k and 100k resistors to the sense circuit. When the comparator first trips this further decreases the voltage sensed by the comparator by 1.2v nominally providing hysteresis. Thus the junction of the thermister and bulb must rise to 9.2v nominally instead of 8v to turn the comparator back off.

Schematic. The three ground symbols will go to AUX Power Neg Terminal

Here is the test circuit still on the breadboard, I've yet to solder it up on a circuit board. People were asking what a breadboard was.

Not sure what the issue with your circuit may be, but an NPN transistor is not well suited to what we are trying to do. PNP works much better. Post a schematic....

well, I DID have plans to attempt some riding this month. It was to be my first trip around the block (block is about 1 mile trip) since my bike got hit in January of 2019. The club we belong to has canceled their Oregon 250 and it looks like the Oregon 500 (a one day ride) will be at least postponed until June this year instead of May.
Some friends have made a list of various rides we were going to try, but for now I think I will just try my around the block rides. So far I've only made it out the drive and down the block, then back home for a rest. I get lots of U turn practice anyway.

Hi DenverWinger:
Here is my schematic as I remember the values; as I said there is no way to look at the inners now, and all was done by trial, even the Tr. choice; (will have to do all again from scratch)


Perhaps it need some more resistors as you did and a work around it.
My plan was to have 3 male spade and 3 female connectors soldered rigid to the circuit board (I need to do a little more work on that) so for now I just used them clipped on short piece of wire, this way I also get power for the IC right there (by the fuel pump).
Regards, Mario

Never stopped riding was out yesterday and today, we like riding the twisty mountain roads enjoying spring and all the new life, today we both knoticed that all the state game land parking lots were full, went to a wildlife preserve and for the first time ever the parking lot was full and there were bikes everywhere we passed over 100 bikes and only put about 90 miles on the bike. Not many miles but a whole lot of smiles.😁

Yesterday I replaced the spark plugs and cleaned the air cleaner (it wasn't to dirty), today I'll put the bike back together (could Honda had made it more difficult to get to an air filter) and change the oil, damn, I'm looking forward to riding.

We have a couple of trips planned, one is to Idaho Falls for a meet & greet at the end of June and the other is a ride with my granddaughter, she wants to take pictures of the ghost towns in Oregon, so we are planning a weekend ride in July.

I have had the weather to ride but no time!

I am in the process of preparing my house for sale. Been throwing things away (Amazing what you accumulate in 28 years) and I still have to trailer up my 3 bikes and transport them to my friends house where they will wait patiently for me to come and get them.

Once I get my house on the market, then I can relax and ride some. Carefully so I avoid any trips to the hospital.

Oh, but of course, I forgot about the snow coming in on Sunday.

Ride Safe!

Looking better now
Looking better now

Oh, went over "just a few things" on my 83 Interstate...
Seat cover, timing belts, valve adjustment, thermostat, fan switch, changed all fluids, braided brake lines, new tires, a quick paint job. Also ripped out all the casually rigged wiring the previous owner had added- including the stereo....anyone want a stereo?
Still need to do the front brakes, the left rotor is a little uneven in hard braking, probably warped.

I Finished up my "Low Fuel Light" circuit, it's now built on a circuit board with a quick connector, and set up to fit on the back of the MaxTow Volt and Oil Pressure gauges I've installed in an Unobtanium 2.0.

In the last picture you'll see a light bulb in between the two gauges, 12v aux power flows thru this bulb and thru the Sensor Thermister in the fuel tank. This bulb replaces the Low Fuel Light in the dash, if the fuel is low, this replacement bulb will glow dimly like the dash light did.

The circuitry detects the current flow thru this dimly lit bulb, switching the transistor "On", which provides ground to the low fuel light in the dash, lighting it brightly.

I plan to paint the circuit board with rubber cement, that will keep moisture out of the circuit, but will still allow me to peel the rubber off if I want to tweak the voltage divider resistor values.

Nice and warm today, back to pulling off Tupperware to get all this stuff wired up, and add other accessories that are still sitting on the workbench where they do no good.... :shock:

Well the pub is closed


The church is closed


I've emptied my cellar - I was saving this one.


The garden is done - even the furniture restored




the bikes have never been as clean


even the wife's pushbike


I am getting desperate now

All that space in your garage!!
How do you do it?
In my garage space is so tight to make full use of my lathe I had to cut a hole in the adjacent cupboard.

So far this year I have moved three full loads of wood chips, 3 yards of gravel and 10 railroad ties for various outside projects. I will still have another 3 yards of gravel and another load of wood chips.


Over the weekend I built a rock path leading from the front yard into the backyard. It’s just gravel for now, not sure what we want to do. The main purpose is for getting a wheelbarrow full of wood chips into the backyard.
