Question about 2003 Chevrolet Tahoe

1 Answer

Battery not charging light. wont start

I have a 2004 chevy Tahoe. Noticed before gauges dropping for battery and running a little rough. I replaced the battery and alternator. Battery read between 9-14 in the middle lower than before the problem. Then the battery light came on. Tried driving it and the dash display read battery not charging so I parked it. Went out jumped the vehicle. Ran for about 40 sec and all gauges dropped as if shut off. Vehicle began running really rough wanting to die. gave a little gas and boom it shut off. Battery was then dead and would not restart.

You have so sort of wiring issue, check the battery supply to the fuse box under the hood, it may be corroded.

SOURCE: 98 tahoe wont hold charge

Sounds like you have a bare wire somewhere that is touching metal and grounding out. Probably a starter cable. Try unhooking the battery, check the voltage of the battery, then hook the cable back up, watching for sparks from the cable. After you get it hooked back up, check the voltage again. If you see a small spark, it is normal. If you see a big spark, you have a wire that is touching something it is not supposed to.

My 2003 chevy tahoe won't start in the morning


Many possible causes....Too little info to make an intelligent suggestion. Try charging the problem vehicle's battery with jumper cables for 2 minutes with the supply vehicle running at fast idle (or about 1500-2000 RPM, if it is tachometer equipped) before you try to crank the problem vehicle on a cold morning. If it starts right up, you likely have a weak battery that needs replacing.

14 is good, (10 is bad). Any other issues with the electrical system?
The gauge may just be off a little. If you put a voltmeter on the battery with engine running, it should show anywhere from about 13.5-14.5 volts. That's the alternator output to charge the battery and run the car's electrical systems.
If voltage truly dropped to 10 volts when car was running, I think your check engine light would come on, and there would be serious issues with lights flickering and dimming. Check the alternator output. Good luck.

Unknown Driver on my 2004 chevy Tahoe


Hi:
When your vehicle says : unknown driver, instead of Driver 1 or driver 2, you have had your battery totally dead. so dead that all the programming was lost, the part about not staying started, or not going into gear is a bit baffling, unless your alternator is the real problem, and the battery has just enough charge to barely start your truck, and may need to be fully charged first and stay running . You will need to do remote and seat reprogramming, when you get this figured out

My 2003 chevy tahoe, died while i was driving home. when i tried to start it, nothing happens. it doesnt try to crank or turn over, nothing happens, now my ABS and battery light is on.


OK if only 4 months old, charge it with an external battery charger. Once vehicle is running the quick and still most valid test I make is:
Running, with no accessories on, charge volts on volt meter (not dash gauge) should read between 12.9 &14volts. Turn all accessories and headlights on high beam. Volts should not read below 12.5v at idle and should not creep lower after running at any time, even after ten or fifteen minutes. If voltaqge is not as specified alternator has failed and needs replacement.
