Temp and fuel gauge

Postby dawgout81 » Sun Apr 24, 2011 7:47 pm



Just got a 1981 Interstate. The fuel and temperature guages are not reading at all. The man I got it from thought it was some type of electrical relay or something like that.
Does anyone have advice on this?
Thanks!

Went for my first ride of 104 miles today.....first warm weather here in 3 weeks.......first ride on the "new" bike....NICE!!

I just installed the new regulator. Temp works, fuel doesn't.

I think my problem is ME. In taking the back cover off in the small area between the gauges and the fairing, somewhere along the line I disconnected a yellow wire. I pretty sure it came from one of the "gauge bus" spots. I now have that yellow wire connected to the same spot that nut #29 and lock washer #31 connect the black wire from the regulator to (the far left post of 4 of them along the back of the gauges while standing at the front of the bike looking toward the back through the windshield).

So my black wire from the regulator and the yellow are on the same electrical post right behind the fuel gauge.....I'm guessing this is my problem....any ideas.

Thanks much for the help.

That yellow (actually yellow with white stripe) wire connects the fuel gauge to the fuel sender. So the +7 volts comes from the regulator, to that nut you attached the black wire to, from there into the fuel gauge, and from there, through the yellow/white wire, to the fuel sender. So that wire should most definitely not be connected to the same place as the black wire from the regulator.

The regulator's black wire should connect to the post in the middle, between the two gauges - you can see it connects to both gauges from there, as it supplies 7 volts to both of them. The fact that your temperature gauge is working says you've got the black wire in the right spot, but you've got the yellow wire in the wrong place. Follow the wires coming from the fuel gauge - one of them will be connected to the same bus that the black regulator wire is connected to. The other wire will be connected to the place that your yellow wire should be connected to.

Thanks,
I'm just dangerous enough to get myself mixed up some, but with this bike and your great site and willlingness to help, I'm looking forward to becoming a better mechanic, having this bike in top notch shape and having some great rides.

Hello , i have that problem on my new to me 1981 Gl1100 and it states in the description as follow.

"Left in a failed state, it can cause damage - allowing a full 12 volts into your temperature and fuel gauges, destroying the delicate coils inside!

Just purchased the bike and not sure how long it has been in this state? Should i try it anyway or would the damage already done?

If the gauges still move, they're OK. What can happen is the higher voltage can burn out a coil, which causes the gauge to stop working altogether, it will always register zero. Put the new 7 volt regulator in, and you will be fine, and your gauges will work again.

HI as we're on temp and fuel gauge , mine work ok BUT no back lighting .Is there a fuse somewhere other than the main fuse box as all the fuses are ok. If its bulbs I SUPPOSE its fairing off to reach them but I would sure like test out before removing fairing.

They're connected directly to the same wires that light up the speedometer and tachometer. So if they're working, it's not a fuse - that means either the bulb is gone, or a bad connection. Most likely the bulb.

You do not need to take the fairing off. Just take the windshield off and work from thee.

I have a 82 wing with the temp gauge not working. I was able to score another complete set of 4 gauges (ambient air temp, clock, volt & alt) everything works but the ambient temp on both set of gauges. I tried taking the probe from both gauges and putting them in ice water then in hot water (40deg C). I got no movement on either gauge? Is there any other way of checking this one gauge. (Temp)? :?: I don't find it too big of a problem to get at the probe on the bike. All it takes is to remove the left hand signal light.

If the ambient temp wire has a hole it. It has lost it's gas that is contained inside to give the temp and I have not heard of a way to fix it.

Thanks...... I will check out both gauges and get back to you. If they both have holes in the wire I would suspect that the fluid has been lost and there will be no way to replace it? If this is the case do you know where I might be able to get another gauge?
Thanks again

Hi I don't think it is relevent but feeling around the back of the consul maybe to jiggle some wires which I didn't find I found the rev counter connection was unscrewed, and re-connected it and I had just replaced indicator relay [3 pin] and on testing indicators and brake lights noticed lights have now appeared in the speedo ,rev counter, and fuel & temp gauge :? . Done something right but really don't know what. But its good have it all working again :D looking forward to a run this weekend :D ya hoo

I was finally able to get back to my bike and have a look at the gauge. The one on the bench has a light and a copper wire with a tube on the end. If I put heat to the bulb I can get the needle to move from -30 to 0. it won't go any higher. I have taken a couple of pictures but don't know how to paste them yet. I'm not sure but I don't think there is any fluid in the copper tube/wire? Ok I just went in and found out how to upload my photos so here they are

sorry dawgout81

Not trying to hijack your thread. Maybe wandering man can start a new thread.
Your pics do not look like the ones I have and seen.

Hi , the wire I think is a fine tube from the bulb to the gauge and if its working at all like you say maybe the gauge is actual the problem .I once had a combined vaccum and pressure gauge and it turned out that pointer had actually slipped on its shaft.
Hope this helps

Thats a good thought I will take the gauge apart to find out. Let you know if I find anything.

You're thinking of the altimeter, not the ambient temp gauge.

They're far and few between. eBay, parts sites...good luck!
