I'll be going what ever the speed limit is and all of a sudden all of my gauges shoot to the right.
They will stay that way for anywhere from seconds. Then they will go all the way to the left like the car isn't running for the same amount of time. Then goes right back to normal. My cousin has replaced my Alternator a few months ago and I got a new battery bout the same time.
Also my car is misfiring when I accelerate and I know that's spark plugs so those are getting changed this weekend. My uncle cousin and myself are so confused as to why my gauges are screwing up like they are. Please any ideas will be wonderful cause I cant get a new car at this time due to finances.
S10 Help ASAP MY GAUGES GOING CRAZY?
On most vehicles this normally happens when you first turn the key to start the car. If it happens while driving it is most likely either a short in the wiring in the dash or even though the battery and alternator are new, the battery voltage may be low.
It is possible to get a defective battery or alternator out of the box. I would go to an auto parts store and ask them to test the battery and alternator. They will be able to do this in the parking lot without you having to remove them from the car.

Sometimes the ground strap to the body of the car can come loose.I bought this Chevrolet z71 4x4 on Sep 10 I got a good deal on it if I can fix the problem.
All the gauges are dead, no function. The security light flashes 5 time then the battery light will flash once. Then repeat. I have no odometer lit at all. The shift position out as well. I put a used cluster panel in from the auto salvage yard. I did get a odometer and shift position to come on, but still no gauges. So I didn't buy it. Someone told me I would have to have a dealer to plug in the cluster and program it to work.
Does this sound right to anyone else? The low fuel light came on and the fuel gauge read empty right after I filled the tank. Then, very slowly, the needle on the fuel gauge started to rise, and after about 15 minutes of driving was finally registering what seemed to be the correct amount. This also happened on the previous fill-up, but that time the fuel gauge registered empty and then suddenly jumped up to the correct level. This problem started shortly after I returned from Iraq. First it was the fuel gauge malfunctioning, reading low fuel when knew good and well it was full.
Hardly fair if I do say, to fix one sensor, however i do realize the amount of labor; lifting bed, draining tank, etc Oh that's right, that would mean GM would have to take responsibility. Moving on, now the low coolant light comes on when I know the level is fine.Although we're writing about this Chevrolet intermittent electrical problem, the issue also occurs on GMC and Cadillac trucks.
My customers have been complaining about this for years, but every time they show up with the vehicle everything worked properly. And this is why intermittent electrical problems remain some of the worst issues to solve. With that said, enough people have had the issue, that the problem finally got solved.
Customers complain about intermittent power outages throughout the vehicle. Sometimes the power door lock starts going off by itself or the dash lights go out. In extreme circumstances the entire truck loses power. Whenever crazy things like this happen my mind starts going to a ground connection problem.
When symptoms become widespread and randomized poor electrical connections become suspect. Nevertheless, intermittent ground connections can cause some really crazy side effects. In this situation we have a failure of the main ground cable that runs from the battery to the engine block and frame. I have seen several issues with this one ground cable in many years, make and model General Motors products. However, the vehicle that brought me a successful diagnosis became a Chevrolet Tahoe.
Thank God for this truck. The Chevrolet intermittent electrical problem got so bad the problem finally occurred in front of me. When I checked the ground cable for tightness at the battery I saw looseness at the actual crimp fitting that holds the negative cable in place.
Unfortunately, this is not the only problem I found with this cable. I'm no stranger to complicated automotive electrical problems. But the issue with this Chevrolet negative battery cable had me scratching my head. Let me tell you why. As I mentioned the connection where the cable goes into the battery terminal was loose.
So I thought I'll just fix this connection and everything will be fine. However that wasn't the case. I pulled the cable out, cleaned the end of it and then soldered it back into the battery terminal.
However, the intermittent electrical connectivity of the truck remained. So I went to the other ends of the ground connection. One is located on the frame of the truck and the other is on the engine block.
We'll get into how to find these connections in the next section. After performing the same clean and solder repair of the ends of the cable the problem persisted.
At this point I realized that I would have to get a new cable. Highway robbery if you asked me.
We fixed the truck by replacing the battery cable. It appears that water somehow infiltrates the covering of the cable and rots out the cable from the inside.Why the gauges and door locks go crazy on some Chevy vehicles and how to fix it
This is not the end of the story, because the positive battery cable looks identical in construction to the negative side. When I grabbed the positive cable and started wiggling it, I got a couple of dropouts of the electrical system.
It's for this reason that I think you should seriously consider replacing both the positive and negative side battery cables to eliminate this Chevrolet intermittent electrical problem once and for all. Let's talk about the negative side first. The battery is on the passenger side of the engine compartment near the firewall.After a few minutes everything went dead, my lights, windshield wipers, gauges, everything.
But the truck still runs. It loses some power. When you turn it off, then turn it back on the battery gauge reads about 9.
Chevrolet Intermittent Electrical Problem
It is a brand new battery and alternator. What do I need to do? Sounds like a bad alternator. Just because it is a new one does not mean it is not bad.
Unless you just got some bad connections on your battery. You can try cleaning them that might help. You must add extra battery grounds to the frame and engine. Make certain all the battery positive connections are solid. A loose engine starter motor will wreck havic. You must have solid battery-to frame-to engine ground straps. They depend on feeding the dealerships with calculated break-downs!
