Perhaps your alternator is faulty or drive belt slipping or battery could be faulty.
Check battery connections and main earth strap.
Have battery tested and then check voltage goes up as you rev up to see if it's charging. (should reach 14.5v)
If there are no warning lights the battery is the prime candidate

I think you may have destroyed your battery or the electronics?

First check your fuses are all good

If that don't fix it.

Check the voltage of battery Red to + Black to -
Meter should give a positive reading say 12-14Volts DC

If this is what you get then you may need a Auto-electrician to check electronics and wiring.

You need to find the current drain. Charge the battery, then disconnect the Negative terminal. Now connect a 12v tester or a automotive lamp between the terminal and the battery post. This will put the tester/lamp in series with the current flow and they will light if there is any current drain. So assumming the light is on, now pull fuses one at a time until the light goes out. Remember to keep the door light switch from being activated as that will cause it's own current flow. Do not turn on the ingition since the failure happened over night while the truck was off and closed. There will be a normal very small current flow all the time to power the radio preset memory and perhaps an alarm but that flow will barely light the lamp. If the lamp is blown due to a real high current flow then you will neet an ammeter with about a 50 amp current rating.

Well, when the battery goes dead or is disconnected, the vehicle's computer has to re-learn all the parameters while it is in operation. Perhaps after several trips it will work normally.

How do you if the alternator is bad


in my experience when your car is dead and you get a boost it will go dead again in a very short time. this means your alternator is not charging your battery so it needs replaced. boosting your car and letting it run should charge up even a weaker"battery if you have to boost everytime you shut the car off your alternator is toast"and it will kill your battery as well if you don't replace. it hope this helps

There is a switch above the break peddle that is adjustable for the break lights. This is running your battery down that is why the gauges are jumping. Change the battery.. If it is 5 years old draining it dead will kill the cells. Hope this helps.

2000 Alero Security light flashing and wont start


With the new lock cylinder in it, turn the key on. The security light should blink. Leave the key on for 10 minutes, the security light will quit blinking and go out after 10 min. This will reprogram your security system and the car should start. Also leave a battery charger on it while the key is on, If the battery goes dead during the 10 minute reprogram sequence, you will have to start over again.
