Is your battery more than five years old? If so, it's probably dead. Just take it to some auto parts store and get it tested.

 

Do you have a multitester or voltmeter? Check and see if the voltage is up. Did you tighten the negative terminal while the car was running? That could blow a fuse. Are the battery terminals corroded at all? Is the clear eye on top showing through green? these cars all use maintanance-free battery's right? never mind all that, just change the battery, check the fuses, maybe cut the terminals off the battery cables and replace them with new ones... while your at it you can relocate the battery to the back of the car...

 

its bout 3 years old no corrision

 

You could have a parasitic draw from your battery when the car is parked. A quick way to check this is to disconnect your ground terminal from your battery and hook an automotive test light between your battery and ground cable. Before disconnecting the battery, be sure everything is turned off, doors are closed (driver's window down) and if you have a hood light, take the bulb out.

If the test light doesn't light, it's more than likely the battery is bad. Before replacing it though, I recommend having a complete charging system test done at a local auto repair facility (A lot of places do this for free as a courtesy service).

If the test light lights up (even dimly), you have a draw. At this point, remove fuses from your fuse block until the light goes out. This will isolate which circuit the draw is on. An electrical schematic of your car will really help you at this point.
