Fuel Gauge Not working - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Green72GMC · 04-24-2003, 01:14 PM

Hey all, My fuel gauge is not working. I think my printed circuit is messed up, I was wondering if I could just cut the wires from the adapter and wire it up direct to the gauge instead of going through the circuit. (None of my stock gauges worked except the fuel gauge anyway)

Plain 72 · 04-24-2003, 05:34 PM

What is the guage doing? Does it go way past full? Mine was doing that and I found the single wire that hooks on the sending unit had a bad connection.

Green72GMC · 04-24-2003, 05:36 PM

nope, it dont even move.

Someone on this board should be able to ship you a complete used dash cluster for what you would pay to repair yours.
I see them all the time at swap meets for $10 to $25.
Start a thread on the parts board.
Want to buy dash cluster with good printed circuit and find one close by to save on shipping or make a trip to the local salvage yard.

Also the bezels are different for some years as some have choke holes in the bezels and some don’t. Then there is the three-hole type with the idiot lights instead of gauges.

Just a thought

yea, I have an idiot light one that came out of my dad's '69 chevy that has been sittin up for 25 years. But mine has the gauges and im tempted to convert mine to an idiot light one.

Pull your inst panel off, and trace the printed wires from the 2 posts on the back of the guage, to where they go into the harness. If the printed circuit is bad, you'll be able to see it.
I jumped the bad circuit on mine.

i've got a 7 hole dash setup with a working printed circuit. All guages work except for the temp guage i think. It might work but i never tried it. You can have it for 20 bucks + shipping... I paid 30 at the yard for it.

Green72GMC · 04-25-2003, 05:42 PM

longhornmail: To jump it do I just cut the 2 wires off the adapter and attach it to the two posts?

Longhorn Man · 04-25-2003, 08:24 PM

What I did was run a mall piece of wire from the nut on the guage, and tucked the other end under the plug on the proper terminal. It was a PITA to do, but I no longer need the broom stick to dip into my tank.

Green72GMC · 04-25-2003, 08:26 PM

K thanks man.

I've seem those little line splicer connectors ... the kind that clip onto the main line and allow another lead to go to the fuel post. You can connect them to the fuse harness line instead of the plug... depend on how secure you want it and if you dare to splice into the harness. Was a time here when tach printed circuits were hard to find. A few years back when when I saw that type fix done.
