IN cluster wiring the earth wire is incorporated in the plugs and is normally plain black. It stays in the harness until it reaches a point where it can be earthed out as most dashes are plastic and will not pass current. A wiring diagram will how where it earths out.

SOURCE: the fuel gauge is'nt working.I tryed to ground it

If your gauge reads full, the wire to the tank unit is grounded. Remove the wire from gauge to tank. The gauge should now read 'empty'. If still reading full, the gauge is faulty, or possibly it's the voltage regulator that supplies reduced voltage to operate the panel instruments. If the voltage at the panel unit is ok, run a makeshift wire along the outside of the vehicle to the tank unit. If it still read full, replace the gauge.

2001 Chevy Silverado - 2500HD, 8.1L V8. Why did all except 2 gauges stop working?


I suggest you take it to a ASE certified repair shop , it sounds like you know nothing about automotive electrical systems . I don't know who told you that a hot wire is touching ! I'd say they don't have a clue either ! From my 30years experience , I'd say the instrument cluster is bad , because I know GM had a lot of problems with them ! But if you still think you want to mess with it , you'll need to pull the instrument cluster out of the vehicle , find a wiring diagram an check the instrument cluster wiring harness an connector for bare wires an check for power an grounds with a DVOM - digital volt ohm meter !
  1. Turn ON the ignition, with the engine OFF.
  2. Observe the IPC.
Does the instrument cluster operate normally?

Go to Testing for Intermittent Conditions and Poor Connections in Wiring Systems
Go to Step 3

  1. Turn OFF the ignition.
  2. Disconnect the IPC.
  3. Turn ON the ignition, with the engine OFF.
  4. Connect a test lamp between the ignition 1 voltage circuit and a good ground.
Does the test lamp illuminate?
--
Go to Step 4
Go to Step 7
Connect a test lamp between the ignition 1 voltage circuit of the IPC and the ground circuit of the IPC.
Does the test lamp illuminate? yes or no
Inspect for poor connections at the harness connector of the IPC. Refer to Testing for Intermittent Conditions and Poor Connections and Connector Repairs in Wiring Systems.
Did you find and correct the condition? yes or no
Repair the open or a high resistance in the ground circuit. Refer to Circuit Testing and Wiring Repairs in Wiring Systems.
Did you complete the repair? yes or no
Replace the IPC. Refer to Instrument Cluster Replacement .
Did you complete the replacement?

08 chevy aveo gauges not working


First I'd check the "meter" fuse (actually all fuses really) located in the cabin fuse box. If these check out, it is likely that a ground wire failed in the gauge unit, and the gauge cluster should be removed to be serviced.

Could be a bad harness, or the grounds could be corroded. Chevy did have some recalls on Silverado clusters. Also the radio fuse under the hood is part of this system. hope this helps.

I have a97 chevy c1500 the fuel gauge never worked,so i put a new sending unit in still dont work gauge reads past full @all times can anyone help


Your problem with you fuel gauge is not the sending unit or the gauge in the cluster. You have a broken ground wire in the the harness that goes to the sending unit. look for broken wires or wires that have bin picked with a test light they will have corrosion

If the sending unit was connected and grounded, I would guess the gauge in the cluster is faulty.

I would like to know if I can wire my autometer guages (electrical) into my instrument cluster with out causing damage. I own a 81 GMC C2500 pickup. Thanks steve sstratford@cogeco.ca


Hello,
If you are looking to install these gauges into your factory cluster it is possible as it is not a computer cluster. I would look into buying a professional cluster made for hotrods that is already done as there is alot of work to do to make the Autometer gauges fit nice and clean. There is a plastic cover over your factory gauge set and it will be dificult to get it cut out and set rite for the new gauge set. maybe if you built your own cluster unit you could use one of these Billet pieces as a template. Thats just a thought I have done this and It looks nice with a rose wood underlayment routered out to fit the gauges.

Fuel gauge bouncing on 2000 chevy tahoe where is fuel pump relay


I had previously replaced the failing fuel pump on my '98 K2500 when it went out entirely. I was ready to replace my 2000 K3500's fuel gauge as it was acting up.
When I started the engine, the gauge would bounce from the middle to way past full then back. It would also jump sporadically while driving on level ground.
I checked the electrical connections at the tank and made sure the frame ground strap located nearby was making good contact. Nothing changed until I removed the instrument panel and cleaned the connections on the back. The fuel gauge seems to be operating correctly now.
There are videos on YouTube that show how to remove the instrument cluster if in doubt. Mine dash has a pop-in plastic bezel followed by 4 screws to hold the cluster in place. It took about a half hour to inspect & clean the dash connection vs. $250 to replace the pump/sending unit combo. Hope this helps.

Tunatic, Personally I would agree to check for a short to ground in the circuit. However, verify the sending unit first, it cost less than $20 and can be replace easily.
Good luck and let me know if you need anymore assistance.
