Fuel Gauge Help

Post by stephenricci » Fri Dec 01, 2017 8:28 am



I am having an issue with my fuel gauge and am looking for a little help. My temp gauge is working fine so, according to what I have read, it is not my 7 volt regulator. The temp gauge needle seems to be sticking. When I fill the tank, the gauge does move but not to the full level but if I tap the gauge it will move up a little. When I shut down, the gauge does not move all the way to the left. Again, if I tap the gauge, it will move to the left but not all the way. My bike is currently disassembled for a Carb refurbish (Randakk's of course). I am also pulling the gas tank to have it cleaned and sealed because of what I found in my carbs. So currently there is no power to the gauge but it still shows a little under 1/4 full. I normally do not rely on my gauge as I am use to using the "gasodometer" but I would like to take care of the issue while she is down. I have ordered the 7 volt regulator offered on this amazing site because I figured that I might as well take care of that while she is taking a nap. Any help or suggestions would be greatly appreciated.

Thanks,
Steve

From what you're describing, I would say the issue is definitely with the gauge itself.

The gauges have damping mechanisms in them, so that they don't jump around when the fuel sloshes in the tank - it takes a while for them to respond to changes. It's possible that this is sticking. Have a look at the gauges themselves and see if they are dirty or obviously otherwise impaired.

Thank you WingAdmin for the very fast response. When I take the gauge off to install your new 7 volt regulator, I will have a look see. Without doing my research first, are there any tips on checking out the gauge condition?

Pull the float (or use a spare). Attach a ground lead and move the float lever while the power is 'on'. Gauge should move correspondingly.

This tests everything in the circuit.

remove the complete gauge assembly and dunk it in distilled white vinegar.

leave it there for a few hours, and swish it around.

in about a day or two, all of the rust will be gone, and the gauge should start working again as it did new.

a gallon of vinegar should give you enough to change out the container two or three times,

be patient, rust did not form overnight, and it won't go away overnight.
but, vinegar will dissolve it all eventually, with no harm to the electrical parts.

Cosmo and John, thanks for the help. I removed the tank yesterday and dropped it off for a good cleaning and sealing at a local shop that does a superb job on gas tanks. My float has been soaking in vinegar for two days now but I do have a spare. I will try the spare to check the circuit as suggested. BTW, my gas gauge still reads 1/4 full. I will pull the temp/fuel gauge to install the new regulator after it arrives. John, are you suggesting that I soak the temp/fuel gauge cluster in vinegar also? That just doesn't sound right. I will be working on the carbs and cleaning/greasing everything up for a couple of weekends so it will be a little while before I get to the gauge issue. Thanks again for the input.

no, not the gauge itself, only the float sensor...

do NOT under any circumstances put a liquid on the gauge itself.

Thanks, that's what I thought. For a minute there I thought that I might have been losing it. Already been soaking for a couple of days now. I did bend the three tabs back and removed the cover first to make sure that the inside gets nice and clean as well. I was also careful not to mess with that tiny, wheeny wire.
