Gauge readings

[Juangzo6]

Is this normal battery and oil gauge readings on a 2003 5.3 Tahoe? Any information helps please and thank you all

looks good to me. if idle was under 20 id be worried.

the battery is over 12 volts so good once again. i you turn the lights and ac on full blast and it drops under 12 youd have a bad alt or bad cables to it. stuffs getting old for all of us....

The rpms are kind of low on the tach. Compare that reading to what a scanner says is the actual idle.

The odometer needle seems a bit low, too, for the key being "on."

If it's fully warmed up I'd expect the coolant temp needle to be closer to straight up. Compare with a scan tool.

Like Fless said
What's your ACTUAL idle? What's your actual road speed (you weren't going backwards while idling)?
Either your oil pressure and coolant temp are on the low side of normal,
or your oil pressure and coolant temp NEEDLES are acting just like your tach and speedo NEEDLES.
So long as your voltage is ACTUALLY over 12 Volts when you turn EVERYTHING on at the same time, you're ok.

Seems like your actual problems are:
your needles seem to read low, and they need checking / repair / replacement
you automatically believe your needles before checking that they're actually representing accurately,
when GMT800 needles are NOTORIOUS for under-reporting.

the clusters have a wide variety of variations and a wide variety of issues across all of them, like bad servos, shorts etc

 

[Fless]

Could just be as simple as the needles not having been put in the correct position after cluster work (like stepper motor replacement).

Does even one exist that has OVER-reporting needles?

As stated above, RPMs look low.

Oil pressure is normal, if your oil is at normal (hot) temperature.

Electrical voltage is most likely OK, as these trucks have a system that lowers the voltage, once the battery is fully charged, to prevent overcharging.

Also as stated above, you should double check these readings with external measurement devices, so that you can obtain a benchmark comparison on how your truck's gauges compare to the external measurement devices.

thank you man

yes my cluster is on its way out man

as far as I remember my roms sit at around 550/600 at Odis fully warned up, and as far as the cluster gauge it is on its way out, I will still go for a drive and test with live data thank you all ur awesome

Scanner on

I am jealous of those gauges that actually show information. On newer GM cars all those numbers are gone.

Yes I love older vehicles for the simplicity

years ago i took the chance with an ebay seller that I shipped my cluster out, they repaired all the bad grounds replaced the stepper motors and added led lights and shipped it back to me, i wish i had them add my trans temp. at the time it was only like $60 to have it done

They / them ... who dis? (In case they're still around)

I dont see the guy i used on ebay anymore but i saved this for future possibility

Pardon Our Interruption...

Everything has went up in price its crazy nd I want the led work done, my life’s a wreck atm I’m just gonna fix the cluster and it’s good after that although once things smooth out I plan on doing a lot to it
