My blazer wouldn't start this morning and I had to jump start it. As I was driving, all and I mean all of the dash warning lights were flashing on and off randomly as I was driving. When I was stopped they were fine.
When I got to my destination and shut off the engine it wouldn't start again. Not even enough juice to even close the power windows.
If the battery doesn't charge it could be either. I would suggest taking the car to Advanced Auto or another reputable company to test the battery and the alternator. The battery could have too many bad cells to maintain a charge or the alternator isn't running. If your battery is older than 4 years that is most likely the culprit.

Usually it means the computer is not accepting the chip in your key. It can be the key, the sensor in the lock cylinder, or something in the security module or computer. You might try another key or lock and unlock the driver's door with the key.
well it sounds like the alternator is not charging properly. car off at battery there should be at least 12.6 volts. jump start car, when running if alternator is good battery voltage should be 14.2 to 14.6 good-day !!
It sound like a relay switch to me..Have someone turn key while you try and locate the clicking Check owners manual for locations of relays.If you find the one clicking you can replace it for around 10 dollars
this is one of two problems (maybe both) ...
1. The battery has been fully discharged before, preventing it from being able to hold a charge properly. This can be tested at a Sears Automotive Center. If the battery is no good, get a replacement and you should be fine (at least for a while). If you are going to go to Sears, have them run a full electrical diagnostic -- if there is something draining your battery while the car is not in use changing the battery will only hide the problem for a few months until the new battery fully discharges, and the same issue with resurface.
2. Your alternator is not charging the battery. It might be pumping out electricity to the wiring that it is connected to, but the charge may not be getting all the way to the battery. Sears can also check this with their diagnostic tools, and should be able to locate and repair the problem for you. Unfortunately, without a VERY expensive diagnostic machine, it is very hard to tell exactly where the problem is occurring .. so taking it in to a shop is probably your best bet.
check alternator output with engine running.you should have 13.5 - 14.5 volts if not alternator not charging.check alternator wiring to battery feed to alternator.check alternator voltage regulator wiring check alternator fuse make drive belt not slipping.and you have the correct cold cranking amp battery.bad old worn out battery cables will cause charging problems.because old battery cables put high resistance on the charging circuit.if battery cables old as vechicle replace them.
Sounds like alternator or battery. Try jump starting car and stop by any good parts store like Autozone, Advance, etc...and have them do FREE charging system test and FREE battery load test. You'll get your answer and FREE
ok get power to truck turn key to on position pull plug off altenater one of then should be hot its call an exciter wire to excit the altenater to starg charging but first before all that check the alt. fuse inside your truck
alternator gone bad, 100%. as the voltage starts dropping, all the lights on the dash will go crazy because the electronics cannot perform their self diagnostics, as they do not have sufficient voltage.
