More than draining it, maybe you have three else conditions (in probability of ocurrence):
- Your battery is worn already (specially if is older than or near 2 years)
- Yor alternator is not charging at all the battery.
- Something in tour electric circuit is draining the battery
- Your alarm have loose contacts wich may consumes (transforming it in heat) more energy that shoud do wen in idle,.

Any car electrician can give you rigth answers.

Yes it can be your Alternator going. It may not be putting out enough power to meet what the car calls for. Your car only starts on th battery and runs off the alternator after running. You can check it out with a volt mter to see if it drops or not. With your car running check to see if it drops when you ut the lighs on and also put your heater fan on, wipers too. If it falls below 13.8 volts then it is getting weak and will need to be replaced.

SOURCE: Buick Regal 2001 LS dashboard lights flash off and on

It turned out the ground wire to the battery was loose, Evidently, it loosened up when driving so mimiced the earlier symptoms because it connection was sporadic. I hooked up to a computer to verify after connection tightened and it came away with no errors or problems.

Too many choice.
3 main areas are fuel, spark, air.
Try a shot of ether, if it fires at all, it is a fuel problem.
Then we can get into more detail.

Modern vehicles need minimum voltage to operate the electronics. It is possible for the vehicle to start, but not run properly dye to the low voltage. Most likely your battery is low, or bad and we intend charge. Also your alternator may be bad.

New starter wont start just click


change battery cables. get rid of those small gauge wires and put wire in that will draw amps. I had one car that would kill battery every year and found out the cables were to light to keep it working properly.. both the positive to the starter and the ground cable are way to small for the car. clicking means it isn't getting enough power to the starter to spin the motor !

Starter gets jammed after fitting and to confirm the same, engage your car in second gear and try pushing front and back and it should release. Try starting thereafter. In most cases it works.

Sounds like the starter. You can try several things but the main idea is to start it to be able to bring it to a mechanic. Disconnect the battery and push on the brake pedal. This will drain the power from the vehicle. Reconnect the battery and try to start the car. The theory behind this is the starter solenoid could be stuck energized. You can also locate the starter slightly tap on the starter and then try to start the vehicle. Also if the vehicle has sacked for some time before you purchased it the battery may not have the cranking amps necessary to start the vehicle. The electrical gizmos will work but it will not be enough to crank the engine. Check the battery is fully charged and possibly try to hook up jumper cables to another vehicle or a jump start Appliance.

Start up issues


Take your starter off and have it checked out. Sounds like it's taking too much power, and possibly killing your battery. A bad starter will drain your battery when the vehicle isn't running.
