the car is having some major issues.the lights are bright when it is off then dim when running.if you shut the car off it will not start again without disconnecting the battery.it just clicks like a bad connection in the battery.i put a new battery and new alternator cause the battery light is on or was.now this.the alternator is charging and the battery is fully charged.any suggestions would be great.it has 2 mechanics stumped.not theft deterrent mod or computer.
