1998 V11 EV basic question (indication)

[Kiwi_Roy]

Nice, I have one the same colour, it started out black then I heard of someone selling all the blue bits, I call it my "bolt on paint job"
There will be 12 Volts on both plugs, the fuel level light has 12 Volts on one side. The sensor draws a small current through the level lamp to chassis but not enough to light the lamp. This current is enough to warm up the sensor when it's not cooled by fuel. If allowed to warm up (above fuel level) the resistance drops, it warms up some more, the resistance drops until the low level lamp lights, they work really well, first of all they start to come on and off as the fuel sloshes around.
If you have the plugs swapped the lamp will come on for sure since the petcock is only 120 Ohms but with 12Volts directly across the level sensor it will burn out in seconds if the fuel drops.
That Harpers price is excellent, grab one if they are in stock (I don't see a picture)
As Wayne pointed out earlier the sensor will measure about 1,000 Ohms at ambient temperature, if it's reading open it's fritzed I'm afraid.

If it is opened, it is toasted.
Assuming you used an auto ranging ohmmeter.

I used a Harbor Freight $2 ohm meter set at 20K.

Sorry, it's fried, don't feel too bad most others are as well, I have one on my V11 Sport, it still works because the plugs aren't interchangeable.
You would be very lucky to find a used one that works, here's what they look like, 2nd from bottom.

The Panasonic sensor I posted earlier replaces the shiny tip you see, but getting access to the wires is a bit tricky the wires are too short to allow you to pull the tip off.

BTW, when I fill up I reset the trip meter to zero and look for fuel at 150 miles, I've only run out once that way your little container is another way.

geees, that Harper's part (fuel sensor) was $125 last time I looked. 

I just called Harper's to order the $50 replacement but it's out of stock until next week.

Then Guzzi will have raised the price.

I've been riding the bike without the low fuel warning.  I've put as much as four gallons in at a pit stop.  As of Sunday, the light came on with just over 100 miles on the odometer.  It's on intermittently at idle.  I blip the throttle and it goes out.  I figured I have a short some place, but when I unplugged the sensor, the light went out.  The sensor reads now 380 ohms.  Strange.


Yes, I've been trying it out as a dual sport.

Nice bike.  The red oval on he side cover (if original) indicates the bike is an early 1998 model.  The later ones had just the Vll script.  Seems like there is a very slight difference somewhere but don't remember what. Yes, the alt light will glow dim when at idle, mine does. 

[Wayne Orwig]

The low fuel sensor reads about 1000 ohms at room temp.

I have a twin to yours, too. I've had mine up to 125mph a couple of times. Rock steady. I think the rpms  was 5k.
I'll be happy to double check if you like 😀
