Question about 1997 Chevrolet Blazer
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!! Battery is good - 6 months old /Alternator is good - tested at Autozone under load. Battery takes a charge and will start vehicle but battery eventually run out of power. Voltage gauge fluctuates and at highway speed dips down to 9 volts and battery light comes on. Seems the more RMPs the lower the voltage. Seems like it could be the voltage regulator but thought that was part of the alternator that tested good.
Check battery voltage when you turn off car. it should be 12.5 volts.if drops 11.0 volts the battery is got a weak cell in it.i bought a sears die hard battery it last 2 years the battery had a defect .it had a bad cell it short out the battery.check alternator wires for defects.

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
