Question about 1997 Chevrolet Blazer

97 Chevy Blazer - good battery, good alternator...still dies???

My Blazer has been through a tough time...
It had been sitting in the same spot for a year and a half.  The battery that is currently in it is about 1 year and a half old.  I finally got the truck fixed about 2 weeks ago.  Everything was fine.  The Alternator was charging the battery and the battery seemed alright.  I made a three hour trip in it and then drove it the next few days....gradually the battery got weaker and weaker...it would start but it took a lot out of its power.  It was dead the other day and I got a jump and it started.  Then I drove it, the alternator is working because the voltage was reading around 14-15 volts and the battery light was not on.  The next day, I went out to start it and it was dead....So I took the battery to Autozone to get it charged and tested....they said it is a good battery and it was around 11 volts, i guess (I'm not too good with cars).  So here is my problem....
Battery is good (apparently) - 1 1/2 years old Alternator is good - two weeks old
Battery takes a charge and can start truck....battery light does not come on during truck being on.
When I turn the key backwards to turn on radio and other electric devices....the battery light comes on and stays on as if there is a problem with this apparently good battery.
Also, a long time ago, the dome light wouldn't ever go out....so I took the bulb out.  Could this be what is draining the battery?  The cigarette ashtray light doesn't ever go out either
Is there a short circuit somewhere?  Do I just need to go get a new battery and hope for the best?  I gotta get this thing running so I can get to work!  Please help!!

If you removed the dome lightbulb then there is no longer a draw from the battery there but if the ashtray light light does not go out then over a period the battery will go dead or drained to the point to not the vehicle

You may have a dying cell in the battery. It will charge and seem OK but won't stay charged for long. Try a load test of the battery

1994 Chevy Blazer problems. Car starts and runs for a bit. Dies later and won't restart. Next day it will start and dies later. Have changed EGR, O2 Sensor, Fuel Pump three times, fuel filter. No luck....


Have you checked the battery after it died. I would check and see if the alternator is putting anything out. If its not, then i would look into the pink and brown ignition wire that runs the alternator and gauges and such. If any problems with this wire those very things happen. Hope this helps.

Electrical system is draining the battery


It could be the alternator or possibly a short somewhere. Make sure that there arent any lites staying on under the good or somewhere that could be draining your battery. When ya sit and idle..turn the wheel sharply to the left then the right..if it dies then a cable may intruding on your wiring.

Loss in fuel pressure


Need a new battery first, or charge the battery...if the battery is over 3 years old, I would just replace it, also may need a higher output alternator with more amps, to run the electronic fuel injection, fuel pump, and ignition etc...

It sounds to me as though you may have an alternator concern and when it is running all it using is the battery and will die when the battery runs down.I would charge the battery up and start the truck then using a digital volt meter and take a voltage reading at the battery with the lights on and the engine running it should read between 13.1 volts and 15 volts if it doesnt you probably need an alternator.
Let me know

There are no free full diagrams on the net, you need to charge and test the battery, clean the battery cables and run a voltage drop test as well, replace them if the are badly corroded. Kragen will test the battery for free.
