Battery light on

Sounds like you may have a bad drive belt or belt tensioner. There isnt much room on those cars, but you will need to see if the tensioner is holding tension on the belt.If it is, remove the belt and see if any of the accessories are rough when turned by hand. Since the belt has been slipping, a new one may be needed

Lets check this guide out

Hello -

If you can narrow the odor down to the type that would help. You know it isn't fuel or antifreeze. Then is it rubber, electrical, oil something like that?

Next, sounds like it isn't getting enough power and is getting ready to die, ie battery lights etc, it may be a belt slipping..... So do the below and do a good visual inspection on the belt.

The nice thing about the below, it is free.

Please go to Auto Zone or O'Reilly's and for FREE they can pull the codes to the car. Most important: Once they check your codes, if they find something and you don't get it fixed and need to get back with us, please make sure you tell us exactly what the code was, number and all. Example, if the code was E0568 O2 Sensor bad. Then make sure you give us all of that. While there for FREE also they can bring their tester out and check your battery, alternator and starter.

If the above doesn't show anything, we may need to do the below test... You can anyway if you would like.

We need to figure out if it is electrical or fuel related. Pull a plug wire off of the spark plug and insert something into the end of it and have someone try to start the car and have the metal object really close to a piece of metal on the engine and see if you are getting a good strong popping blue spark. Don't have your hands on any part of the metal! If there is no spark, then it is electrical. If you are getting good spark then you need to get a fuel pressure check on the fuel pump to ensure it is putting out okay.

Let me know what you find out and we will take it from there.

Also, if you need to get back with me let me know what the 8th digit of your VIN is.

You need to have the charging system tested first. Local part stores such as AutoZone will test your alternator and battery for free of charge, both on and off of vehicle. Post results of the tests. If after replacement of the defective battery and/or alternator, the speedo is still not registering we can deal with that then.

Okay, check your fuses.

Just because battery is replaced doesn't mean the alternator is good. If alternator is faulty it will eventually drain the new battery too. You need to have it tested.

Do you have a multimeter to do some testing?

When you get the multimeter and get the battery charged let me know. We will go from there.

If I were you I'd get the alternator tested soon, Check the belt first! It sounds like the battery is not being charged.

Have someone else check the wiring from the alternator to the battery. Simple test. With the engine running, use a voltmeter to check the voltage on the alternator. You should have more than 13 volts, but less than 15.9 volts. Then test the battery (still with engine running). You should have about the same voltage you have at the alternator.

If the voltage fluctuates too much, than the voltage regulator is faulty. I am almost certain that the regular is a part of your computer.

Check alternator belt
check charging system and fuses
do an alternator test

Have alt. Checked again most likely a bad diode.
