The fuel gauge on my Fazer 600 shows full all the time! Is this a known fault on this bike? If so what is the cure?
-
:eek once you have filled up .. you need to ride a few miles... :rolleyes
Unless you have one of those miracle bikes that runs on air.... :rollin
Wish mine was full all the time... im usually rooting around my deep pockets for the last pennies for some petrol
Seriously though... in the petrol tank.. stuck sender unit.. maybe give it wiggle or check the wires coming out of the bottom of the tank and make sure they are still connected to the loom...???
-
Could also be a wire shorting to earth, check your wiring from the tank sender all the way back.
-
Thanks for the feedback lads. I will bite on the bullet then and get the multitester out. Thought it was best to check if there was a known fault on these models that may have saved a lot of hassle troubleshooting ;)
:'(

Interesting, when mines nearly empty the gauge goes up to full sometimes, will check wiring also.

Did you sort out your fuel gauge? If so what did you find? :rolleyes
-
No I have not got round to it yet. I'll post on here when I do, probably over the weekend :rolleyes

Looks like i'll have to do similar.
Mine either shows below empty, above full or half when it's actually full.
Recently had the fuel warning light decide not to warn me. Had to have the bike picked up this morning which was embarrassing...
-
had same problem, but thankfully it is sorted. 1 time it would show full and the next it would show empty even after I fill up. What I found after stripping a few things off was that the terminals under the tank for the sender unit were a bit green and the rubber cover was twisted. Dismantled the tank, cleaned the terminals, untwisted the rubber cover, put a piece of sponge on the frame where the fuel pump is as when the tank is lowered the terminals maybe touching and earthing against the crossbar under the tank. Did all this and since then had accurate readings on my gauge. :)

I will also try this.

Cheers, I'll have a look at this myself. It never really occured to me that a fuel gauge on a bike could be reliable so I just try to remember to fill up at around 130 miles. It would be nice to have it working properly though

Interesting....my fuel gauge has similar 'episodes'. I began restoration back in 2011 ensuring all terminals were cleaned & greased, so I'd be surprised if mine has become corroded again in that time. However, I intend to finish the resto' over this winter & will check again.
Could it possibly be the tank sensor/sender...?

Had a similar problem recently and fixed it over Christmas, forgot to take a few pictures.
As most may know it uses a potentiometer which changes resistance as the level of fuel drops. It has a small levers which rotate across a resistive track to change the resistance. Sometimes the tracks wear or the lever wears in the holder.
I removed the sender unit and the bar which holds the float felt like it had to much play on the potentiometer side. This is held in place with a spring washer with a washer under it.
Using a pliers I pushed the spring washer down more to tighten it up and it appears to have resolved the problem.
-
Spring washer with a washer,resistive track,potentiometer, ????? Eh
shame you forgot to take pictures
-
If you remove the sender the spring washer and washer are fairly obvious. If I get time this week I will take it off again and take a picture
-
Will have to do this on mine, shame ive just brimmed the tank.
-
I started having problems with my fuel gauge yesterday as well. The tank is full but the gauge jumps all around, showing half-full, then empty, then reserve light goes on, then off, etc.
I sprayed some WD40 on contacts below the tank, but it didn't help.
What should I try next? I didn't understand a word here (sorry, eng is not my native language):

See picture

Thanks, will try tomorrow!

Need to check mine out soon….often my fuel gauge shows full at the same time the reserve light is on..!
-
Just to add to the variety, my fuel gauge only works when I am doing 5k+ RPM. On idle or low speading, it keeps moving down and down and eventually low fuel warning light comes up, but as soon as I pick up decent speed, needle starts creeping back up again and when it works the reading is correct. Never bothered me too much as I always (and need to) fill up every other day.

You were right.
One of these needles wasn't touching the contact board, due to loose washer.
I fixed it now, but more importantly, I think I know what caused it to get loose.
The bar which holds the float is on easy spot to get hit by fuel pistol while refueling, so, if you insert the pistol too low, you'll probably hit it and step by step cause further loosening of the washer.
I advise caution when inserting the pistol to avoid that...

Here we go again......I've finished my rebuild at last & during the latter stages of the process I did indeed, address my fuel gauge/sender issues. However, despite all advice applied to my sender/wires, my fault persists.
Is it possible to install a picture of my Fazer here anyplace..?

Posting a pic here's easy....
In the same way you replied to the message in the thread....
Go down a wee bit it says Additional Options, press that and then Add attachment then choose file, that's it, post your pic that way.
Oh that's providing your using a phone, think on computer it's easier :)
edit: it's just the same way!
-
Excellent, thank you. Pic should emerge...............?
-
Your welcome.
You can now post like that in any thread your on, easy eh?
Yes both pics showing fine :)
Nice colour scheme :)
-
That is a very clean bike.
What did you do to the swingarm? is it painted?
-
What did you do to the swingarm? is it painted?
I was wondering that too, looks a nice and clean job but also noticed the notches at the rear bolt are not visible, don't think that's a good idea :thumbdown
-
Swingarm painted, re-anodising a bit too expensive! I try to do all the work to minimise costs. Plating however, is not within my capabillity.
Yes, the alignment marks are there for me to see. The trick is to file the grooves a little prior to paint application.
-
why do i have to be different...
took mine apart and was greeted with this.

Well, this seems a continuous story! I've now addressed the wiring/plug/socket, tightening the washer, ensuring the cover fits over correctly.....& still my guage reads full when it pleases.
-
I've had this issue with my fuel gauge this week, after removing the gauge and testing and it all checking out ok I noticed one of the terminals on the fuel sender had been rubbing on the frame causing the sender to earth out and the gauge to read full. After finding this i repaired the insulation and put some foam on the frame to prevent it happening again.
-
Well, I'm pleased to see this issue remains constantly in progress. I have tried every cure mentioned herein, without success. In fact, over tightening the small washer on the sender appeared to produce a very slow gauge reading response. So, if a 'permanent' cure is found, I'm still anxious to read more.......
-
Hi all. I've been around the block on this fuel gauge thingy, new sender & all! I've yet to acquire another set of clox to try however. I now notice that when cold the gauge reads fine. When hot (after a few miles only) the gauge reads full. Would this be the fuel gauge? Anyone tried this route?
