GL1500 Reserve fuel light

I've got a problem with my 1999 SE. The fuel warning light either doesnt come on or comes on and goes out when the fuel level is almost out.
It comes on when you turn the key to accessories before start up so I know the bulb works. I came damn close to running out on the way home cause i thought I still had gas when I actually was running on vapors.

Help...

any suggestions and ideas are greatly appreciated.

And Merry Christmas everyone!

How many miles did you go? I would say get a small 1 or 2 gallon fuel jug and ride till light comes on. I can go 190 to 200 miles on my 1500. It does make you nervous at times waiting to see light come on.
I found out mine works.....it comes on when you are out of fuel. Coming home a couple of years ago and about a mile from my driveway the fuel light came on and a couple of seconds later the engine died. No gas. I do not put much faith in the fuel gage or light. I never want to see the fuel light on again because of this. Like the previous poster said...my trip meter was on nearly 200 miles. From then on I never run much past 160 miles on the trip meter in town or on the road.
Merry Christmas Sid
Go to the reference and FAQs section of the forum for there are two postings on fixing it.

I too go by mileage riden each tank rather than what the gauge shows or the light on. I go @140 miles and usually @5 gal of gas.
I have fixed mine but have only gotten it back on once since fixing it. They are supposed to come on approximately 1 gallon left. They burn out with cool gas hitting the hot filament, so if it has been on, let it cool with ignition off a couple minutes before refueling.

my mechanic was installing other accessories on it. when he finished the gauge wouldnt work. it was so empty that when he pulled the float up it worked. the light never came on on the way to his shop..ive never seen it on till it turn the ignition to acc.
Thanks, I will. aggravating, bike this expensive should have a frigg'in fuel gauge that works.
On my 1800 I found out it comes on with just under 1 gallon left in the tank. I have about 40 miles from when it comes on till I run dry. Found this out in the California desert when a gas station I normally use was closed and I ended up traveling a total of just over 246 miles on the tank. We coasted the last 100 or so yards into the next station.
Ridiculous. they should do a recall on it.
The Thermister (sensor) can easily be replaced... Sorry I don't have the part number offhand, but here's the process:

That is a nice pictorial Alex.
I filled a small jug with fuel so That I could test my light. This was after I had a ride and wanted to check it ( with out extra fuel) I rode 160 miles and Just couldn't help my self from pulling into a gast station. I filled up with 5.3 gals of fuel.
I may have ran out of fuel right after passing the gas station driveway.
Anyway So I held this fuel container until my light came on.
It did come on and I immediately put fuel in it so I don't know how many miles after the light comes on, I could have gone.
I plan to test this again when the weather gets warmer.
Mine has come on a few times this past summer from about 203 to 208 miles on the tank. It then will take 4 1/2 to 5 gallons to fill it up.

That's only 30.2 mpg! You might want to think about a tuneup. The worst mileage I've ever gotten was two up towing my trailer in heavy head winds, and I got 30.1 mpg
Low fuel sensor part number is 37810-MN5-008 and can be ordered from Honda. I know you can enter the part number at Cyclemax, despite it not being listed on parts diagram. I ordered mine from www.PowersportsPlus.com.

You can find the repair procedure by searching "low fuel level sensor GL1500 how to fix".

Fixed mine - REAL easy!

Cheers!

Good info!!

To be honest I took The number from the post before me.I forgot exactly how many miles before the light went on But I do know my milage is not great . I get around 36 highway. and Ive gotten as high as 38 while riding twisties at 50mph average.
I like riding fast oin the highways and it just sucks down fuel like no body's business.
I think I got around low 30 while cruising 75 to 85 with ocassional bursts of 90 .
I seriously have to take my carbs again because cold starts are very painsteaking.
I have no garage so for right now I deal with her as she sits. Im not planning to sit out in the cold for 8 hours.

You may have some vacuum leaks under the carbs so be sure and check for leaks before you pull the carbs off, use carb cleaner with the straw in short sprays in specific locations or an unlit propane torch to search the leaks and when it revs you have found one, could be more than 1 leak.

My 1800 seems to get 2-3 mpg less than most of the 1500's I ride with. One up doing 70-75 I'm usually hitting between 35-38. If I slow down to 55 then I have hit as high as 44. The odd thing is that the higher I get into the mountains the better my gas mileage gets.

I agree with Newday, if your bike is getting hard to start and stumbles at an idle check for air leaks before you pull everything apart.

If your bike is under at least an awning in the winter you can cover it with a blanket and put a 100 watt incandescent bulb below it. That will help it keep a little warmer and make it easier to start.

I don't know it they make an inline water heater for bikes like they do cars, might be worth checking out if you drive in a lot of cold weather.

Wow! Alex the selection of your Aavitar is very reflective of your "pictorial tutoring."
I admire someone with what I call, "technical patience."
