Default Fuel & Temp Gauge Problems For Debra

Debra, in Colorado, just joined us tonight and here is the problem she found on her '60 2Dr Hardtop. She needs your help.

"I just had a new dash pad installed last week. Now my heat gauge and fuel gauges are not working correctly. I thought maybe they mixed up the two wires. I would like to pull the instrument panel to check it myself but I cannot find any instructions. I have a 1960 2 door hardtop. I may have to take it back to the upholster to fix, but I still would like to know how to do it for future light replacement. Thanks for any suggestions."

I have already suggested that she have them pull the instrument panel, check the CVR input and output voltage and see what she is getting out of it in the way of fluctuating 0-6V. I told her that if that CVR unit is putting out 12V it might have taken out her gauge wiring. However, I do NOT know if she put my email address in her address book and received the email I just sent her. So I am posting this here for ya'll to advise her what to look for and how to troubleshoot this. They might have forgotten to hook up the instruments. Who knows what they might have done or missed.

Default Fuel & Temp Gauge Problems For Debra

Here is another email from Debra regarding her fuel and temp gauges. These gauges were working fine until she had someone replace her dash pad... Now she has problems. She will probably have them troubleshoot what went wrong, but Debra wants to learn herself what might have cause this problem, and how to fix it if she has to. I have given her quite a bit of advice for things to check. She does have a shop manual and also a wiring diagram. Here is what she said.

"Ok with your help I now understand and did pull off the fuel/heat gauge. I have the service manual, but that never really explained that the bezels pull straight off. According to the wiring diagrams it all looks correct but I'm wondering about the green wires. In the diagrams it looks like the green wire connects the one side of the fuel garage to one side of the heat gauge. Mine appears to have two distinct green wires that go elsewhere. I am assuming to the voltage regulator. Does that seem right? If it is correct then the problem may just be the adjustment, which I read how to do. I have not checked the voltage outputs yet, so that could be the other issue. Yes, my gauges worked correctly when I took it in. I should probably take it back and make them fix it, but I thought I would take the opportunity to learn myself, and fix it if it was simple. Glad to hear there are more women joining the forums. I recently joined a local car club and there are not many women members there either. It's nice when we are welcome and hopefully that will encourage more women to join in. I know I really enjoy driving my old bird and want to take good care of her. Thanks again! Deb"

Deb also sent me a couple of pix of her '60 Squarebird and I will post them in Our Rides for ya'll to see.

The green wire is split into two wires when it comes off the voltage regulator. One goes to the fuel gauge and one to the temp gauge. I don't know if you have a test light or not but if you do and you put it on one of the green wires you should see it blink off and on with the key on. If you get nothing then it may not be connected. If it's solid then the voltage regulator is probably bad. The voltage regulator is on the instrument panel between the fuel/temp gauge and the speedometer. If you put your hand in the fuel/temp opening you can feel it. It should have two green wires on it. Hope this helps.

John

Default New shocks

My son helped install all new shocks yesterday. I think the old gal still had the originals, they were pretty crusty. We had to cutoff the bolts to get them off. New ones went on pretty easy though. So now the upholstery guy is supposed to look at the gauge problem he created. Hope it's wiring and not that the voltage regulator gave out! Then my only other problem to tackle is no dash lights. I think that may be the switch because I have replaced all the bulbs. It's weird that the overhead works fine, and the headlights work fine, yet they are all on the same switch.

I just got done dealing with this very problem. After putting in new bulbs and changing all the switches, putting everything back together, I had the exact same issue. I put in another new CVR (constant voltage regulator)... but this time I put in a solid state CVR. End of problem. The one I got from one of the vendors( not sure which) was made in China...NG. Also..I was able to pull off the speedo and fuel/temp gauge to reinstall the solid state CVR instead of pulling the entire pannel. You might give that a try if you think the CVR is bad.

Default Fuel & Temp Gauge Problems For Debra

Hi Deb! The problem with your dash lights not working could be the rheostat on the light switch, or the dash lights lead not connected to the headlight switch. The subject of patina buildup on the dash lights rheostat is covered in the Technical Resource Library (TRL) under Headlight Switch. One of our members created a detailed breakdown of how that switch works and how to clean that Rheostat. I assume that you have turned the headlight knob left and right to brighten and lower the dash lights.. If you have and you still have no lights, that rheostat might be bad, or just need a good cleaning. That headlight switch has fuses on the back. I do not recall if one of those fuses controls the dash lights or not. If so, you could have a blown fuse. Take a look at the TRL by clicking on the link under my signature.

Default Fuel/Temp gauge update

Well the upholster was able to fix his mistake on the gauge yesterday with the technical instructions I took down and help from a guy at the Birds Nest. So now it's showing, correctly, a full tank, and the temp gauge is moving. Apparently they were not as gentle with it when they took it out as they claimed! I will have to drive it a little more to see how it registers when warmer. Thanks for the advice on the dash lights. I will tackle that next. Right now I have to get my 1930 Model A ready for the summer and to use at a funeral next week. She's in good shape for 82, just needs an oil change.

Default Fuel & Temp Gauge Problems For Debra

Good Morning, Deb, and I am glad to hear that they were able to figure out what they got wrong when they put things back together, and got the gauges working again. Wow! You own a 1930 Model A! From what you said about her, she is doing good for being 82! If you would like to post a picture of her post it in the Our Rides Forum. Although she is not a Tbird, I am sure the guys and gals would enjoy seeing what an 82 year old Model T looks like!

Default 1930 Model A

I will email you the picture because I haven't figured out how to post them yet! I am a lucky girl with two classic Fords, but I could use a bigger garage!
