Battery warning light is on with weird noise

remove the belt and see how much play is on the alt pulley sounds like a bearing wearing out.

1. Turn the ignition switch to the off position and buckle the seat belt
2. Turn the ignition switch to run (engine does not need to be running), wait for the seat belt light to turn off.
3. Within 60 seconds, unbuckle and rebuckle the drivers seat belt at least 3 times, ending with the seat belt buckled.
4. Turn the ignition key to the off position. A single chime will sound to signify that you have successfully completed the programming.

It can be reactivated by repeating these steps.

The alert will be deactivated but the warning light will continue to stay on will the belt is unfastened.

its the positive wire that goes to the fuse box from the battery. its crimped into the main positive wire. it needs a better connection.

normally only diesels here in spain ,a petrol one isnt worth anything owing to the price of petrol but your problem is something only a dealer with the right software can locate the exact nature of your fault.Its a software fault iam sure but where ?

it mite sound weird but your alternator mite be the prob like the diode on it can be out and it will make your car not start that is why your gauge jump like that so next time your gauge's jump as you try to start it but it just clicks it mite be the alt. hope this will help people out there.

disconnect the battery for 5 minutes and reconnect. sounds like the BCM is froze. it is common for the caravans 2001-2005 this trick usualy works.

1)check the ignition switch is not loose.those things normally come on before starting.unless2) you have a main ground broken somewhere.rodents eat the wiring harness to build a nest and cause mayhem...i have seen that a few times .check the fusebox under the hood on the drivers side

Sounds like you need a starter, or you have a loose wire somewhere under the hood.

Check and see how much your alternate is putting out. Make sure that your battery cables are clean. Check the water in the battery. It sounds more like a connection problem than stater.
