What a clear video! Question? Do you just crimp leads to eyes? Or can I get away with solder and not overheat resister?
@hardscrabblegarage 16 күн бұрын
To build the resistor I soldered them together. To mount it behind the gauge it uses nuts that go on the screw terminals, just like the factory ceramic resistor. Hope that helps, and good luck!

After it was finished did you feel like the notch was cut too far forward?
@hardscrabblegarage 16 күн бұрын
Not at all. The rear end has some forward and back motion, as well as up and down. It moves in an arc defined by the center point of the front leaf spring eye. If you compress the spring as far as you can, the rear axle lines up with the notch - which is the whole point of the notch!

If you remove the clear cover, black plastic, and then screws holding the speedometer in you can remove the cable much easier(through the hole by the headlight switch). Once the speedometer is out the cluster is much easier to remove. When the cluster is back in place you can install the cable then turn the speedometer slightly to line it up with the holes.

What is the issue when a fuel gauge is off??
@femorous Жыл бұрын
Great tips. Maybe you can help me out. I have an 1982 GMC Sierra Classic 1500. I can't switch to the passenger tank as of yesterday. I replaced the switch, nothing. I hooked up a new fuel tank selector valve, nothing. I filled up both tanks and the gauge works perfectly on the driver's side tank. I drove around the gauge drops as usual. I just can't switch to the right side tank. Any help would be appreciated. Thanks!

So something weird is going on, new sending unit, cleaned grounds, but gauge sits at overfull and if I turn on hazards it pulses the needle slightly. Also when I disconnect my sending unit wire from the tank my voltage light just gets more dull (dummy lights). Need help😂
@hardscrabblegarage Жыл бұрын
Well, that really is strange! A couple of things: 1) Test just your meter, out of the truck. Apply the correct voltage... is the meter itself OK? 2) The thing with removing the sending wire affecting the voltage in the whole truck - it sounds almost as if it's trying to use the sending unit ground as the only ground point in the whole truck. With the lights dimming like that, I'd bet another ground is either dirty/rusty or missing. There should be one by the battery to the body, an engine grounding strap somewhere, and depending on model specifics maybe another one or two (gas tank sending unit, etc.). Check and clean all grounds! Also, watch the video again. If the meter sits overfull at 3 o'clock it tells you something.

@@hardscrabblegarage thank you man, I appreciate the time you took to write this! So it seems like the issue was there’s a ground wire on my filler neck that was missing, got a new filler neck and wire and now the gauge seems to be almost accurate. I know I have a tiny bit more than half tank and it’s saying little less than half. So now I’ll do what you said and check the resister that goes on the back of the gauge itself!

I bought a ‘72 C10 many years ago. The seller told me occasionally the gas gauge quits working properly and he had a magnet stuck to the kick panel and said just take that magnet and touch it to the two leads on the back of the gauge and it will start working correctly. It does happen occasionally and the magnet touched to the back of the gauge does correct it.....Any idea on the theory that is taking place?

I've been study how gauges work on 1986- mid 90's I took apart a speedometer cluster just for study from a 86' olds delta 88 and the back of the cluster looks exactly what your showing. I had never seen anything like that . The harness plug fitting in that recessed slot, and just pushing against the ribbon wire circuit . I guess for the light bulbs. I've replace the 2005 pontiac speedometer and gauges steppers But I guess the older inst. clusters use some round thing, there not steppers and there not soldered. and prob. don't break like steppers either. I'm reading in my factory 90 bonneville service manual. that the gas gauge used, it say's the pointer on the fuel gauge is moved by magnetic fields , of two coil's. the coil's are at right angles to each other. battery voltage is applied to the to the "E" coil ( for empty I guess ) & the circuit divides at the opposite end of the coil . One path continues to gnd through the "F" coil. another goes to gnd through the variable resistor of the fuel gauge sender. when the tank is low the resistance of the sender is low. A large flow of current passes throu the "E" coil and the fuel gauge sender resistor this movesa the pointer towards "E" on the scale.when the tank is full the sender resistance is high. More current flow's through the "F" coil, movin the pointer towards "F"on the scale. Say's with the 2 coils operating the pointer, the gauge is not effected by the changes in the voltages of the system
@hardscrabblegarage 16 күн бұрын
That is exactly as I understand it as well. Since both current paths are using the same system voltage, slight variations don't matter. Because the needle is driven by the differential between those two magnetic fields, rather than an arbitrary reference voltage, when system voltage swings up or down it does so on both coils, which cancels out the variance.

I had two 1980 Corvettes and 181 and everything is exactly the same there the circuit boards other than my shift lever is in the console but I was surprised to see that the 85 mile an hour speedometer is also on the truck because that's all the Corvettes have. I sent one to ecklers and had to change to the 165 mph speedometer it came back with 7 miles on it for testing purposes. But trying to find the output gear for the speedometer cable it seems that the Corvette models have about 10 different ones you would have to know the exact ratio of that transmission and your rear end to make it work or it's going to be off I got one through Summit and it was about 10 to 15 miles an hour off. If you look it up they have a variety of colors of the little gear that's permanent in the transmission that's where the big difference is at. I tried buying different ones at O'Reilly's they have them they're very reasonable the 200 mph speedometer but you would have to buy an adapter cable from them to put it into the car they're not the same they won't bolt in and then you're going to have trouble with the transmission gear probably not worth your trouble

Brother if you're going to give advice about resistors, you need to learn the difference between watts and ohms. Also, instead of "wiring up a couple in parallel", just use one of the correct resistance.
@hardscrabblegarage 2 жыл бұрын
Uh, brother, I used to service fire control radar, troubleshooting to the component level. "Wiring up in parallel" two equal resistors is exactly the same as using a single resistor of half the value. As in EXACTLY the same. Total resistance = 1/R1 + 1/R2 ... +1/Rn. This is like the first thing you learn in a basic electricity class... but thanks for your input.

I have a 1980 C10 Big 10 Silverado, None of my gauges are Working. I purchased a new printed circuit board, everything is grounded and working , new wiring harness, fuses .lights etc..., the gauges are 40yrs old. Do the ceramic resistors go bad ?And if they do. Will they cause the gauges not to work? Also do you know what the part number # for the case ceramic resistors. I would like to purchase some.please advise. Any info would be greatly appreciated. Thank you Robert. One more question, I call lmc and ask them if I purchased new gauges would they have resistors applied to the gauges. They didn't know if they did. Anyway do you know if they do? Thanks again.
@hardscrabblegarage 2 жыл бұрын
Keep plugging away at it, you'll eventually get them working. Yes, the ceramic resistors can go bad. And yes, it is possible 40 year old gauges are bad, too! Now, they can also work fine... much depends on condition. Have they been kept dry? Now imagine a truck with a missing window, sitting in a junkyard, open to the elements... different entirely. No idea on the part numbers for the original resistors, sorry. You can Google GM gauge resistors and get many hits, but only a few are links to sellers, and they are often out of stock (which is why I made my own). You should be aware, many repop gauges don't need the resistors at all, it's built-in to the design of the new gauge. This is not always true, but it is often so. If you flip the cluster over and measure voltage on the pins of the gauge, but it does not even move? Likely a bad gauge. Are you sure about the ground being good? It is possible for all of the gauges to fail, but not that common (in the absence of exposure to the elements, flooding, etc.) Good luck!

I'm prepping the truck for paint, so I just purchased a gizmo that will allow a solo guy to lift a pickup truck bed with an ordinary cherry-picker type engine hoist. It basically clamps under the bed rails and gives you a lift point centered in the bed. Search for it - you can find it at Eastwood, and Auto Body Toolmart, to name two places I have no affiliate connection with whatsoever. Good luck!

@hardscrabblegarage 2 жыл бұрын
The fuel gauge-specific ground mentioned in the video is located on the inner surface of the frame's c-channel, a bit forward of the gas tank. The wire connects the sending unit on one end, to a grounding bolt on the frame a short distance away. At least on 1984 models the wire is black, passes through a hole on the frame, and bolts to the inside surface of the frame. Just disconnect it and clean it up. Afterward you can use a DVM to check the resistance to ground from the ground terminal on the sending unit (one probe on the terminal, the other on any clean, bare-metal part of the frame).

I'm not sure, but it could be the gauge itself. You might try taking it out, and squirting it with a cleaner called DeoxIT, the aerosol one. I use it on the volume pots of vintage stereo gear, so it should be safe. Don't get it on the plastic, or the face of the gauge, it might screw them right up! Spray the inside... if it's just dirty, that might help. Otherwise, maybe a new gauge. Hope this helps!
