I have a charade 1986 on petrol no CNG.
At night when i open the car head lights, the RPM drops quite signficantly and engine starts trembling. If I put the car in neutral after some while it shuts down.
Can anyone tell what might the problem be? Seems to be electrical but from where should I start - Distributor, Generator or Coil? The battery though is in good condition ( few months old).
