Steady fuel lamp

Post by windmill » Mon Mar 11, 2019 1:32 am

As most folks know the low fuel lamp is fairly inconsistent due to sloshing fuel, flashing on and off at random for about 20 miles, then stays mostly on but goes out occasionally, then finally stays lit. as such it's more of a reminder than a useful tool.

Knowing a few folks have experimented with them and some manufacturers use them OE, I decided to give one a try. Found a small timer unit and its accessory programming buttons on amazon for about $22.

Setup is fairly straight forward using the online manual, http://docs.timersshop.com/Multifunctional_Timer.pdf
I went with function 10, on/off delay. trigger function 2, On delay 10 seconds, off delay 5 seconds.

Hook up is fairly straight forward, I put it in headlight shell.

Power,
Red + wire to red/white wire on ignition switch.
Black- wire to headlight ground wire.

Float switch,
After determining which float sensor wire is hot and which is switched, I cut the switched wire, and with a 2 strand jumper wire connected,
Blue wire to float sensor end of cut wire.
Yellow wire to harness side of cut wire.

Programming button,
Green to green.
White to white
Black to ground wire tap.

I experimented with on and of delay times and found 10 second delay for on, and 5 second delay for off is spot on.
The fuel light now comes on when there's 1 gallon left no preliminary flashing, no going out when under 1 gallon. The only random operation of the low fuel lamp now is when stopped long enough, and there's sufficient crown in the road to cause fuel to flow from one side of the tank to the other through the cross over hose.

Not a big deal, but its nice to have it actually provide useful, accurate information.

Nice write-up Barry. When you say "float" switch, does that cover all fuel level switches offered from Ural?

It should work, the fuel sensors are simply a 12V + on/off switch.

Those with the optic sensor, or retrofit float sensor might need to go with different delays as they're located and set up differently.

Today with the on delay at 10 seconds, and the off delay at 5 seconds the fuel light came on at 129.9 miles. It did not flash on at all before, and stayed on steady without any flashes for the 5 additional miles I rode. When I fueled up it took 3.98 gallons, meaning I had 1.1 gallons left.

I will continue to monitor it, but I now believe the fuel light will be my primary and most accurate indicator of remaining fuel.

DID IT EVER OCCUR TO YOU - THAT YOU CAN JUST LOOK INTO THE GAS TANK ? I always do this before a ride, + at stop lights - I can even do it rolling.

People did this for 100 years, since inventing motorcycles. All the new nanny-crap is a liability, & can be removed before it causes trouble.

No, not at all, I just fell off the turnip truck, I've never ridden a motorcycle before.

Such words of wisdom, maybe you should have followed them yourself, and responded by writing a letter, putting it in a stamped, addressed envelope, and mailing it. People did this for 1000 years.....because anything new is evil, not to be trusted, and corrupts children.

I've seen the light :idea: , there oughta be a law against low fuel lights.......and make sure you always keep your fuel petcock on reserve. :loco:

Not sure about your Ural, but on the EFI bikes' tanks you remove the cap, first there is the gas pump nozzle size restrictor plate, that leaves two small holes (to let the air out while filing?) and the one larger one for the nozzle. You look down there all you can see is the 'hump back' of the 'bottom' of the tank where is goes over the top frame tube, it's literally just an inch or less below the restrictor plate. If a full tank goes down just a couple of litres, that's it, you've lost sight of the fuel. Look in, can't see bu99er all. :D

The 'hump' is such a pain I have to insert the pump nozzle upright, so that the gas goes backwards into the rear of the tank, if I don't, but do it 'normally', it will risk squirting back out of the filler if the lever is pressed too hard.

This is the non-Retro style tank.

My 07 is the same, not really practical to do except when stopped, if there's sufficient light, and preferably not raining. My M70 has a Monza style cap which just flips open, but further restricts visibility. Does make fueling with vapor recovery nozzles easier though.

The timer on the fuel light makes it accurate and reliable, making continuously looking in the tank a waste of time and effort.

Yup, e-bay special, and fairly common in silver, black is harder to find.

Thanks for the links! This is what I have been looking for. Does this come with the aluminum threaded insert? The pics on the site don't show it.
