Why is a petrol tanker sometimes connected to the ground by means of a wire before petrol in unloaded?

Because even if there's a slight static charge in the tanker, it could ignite the petrol and explode. If it's connected to the ground by a wire, then all the static charge in the truck is removed (ie grounding the truck).

Why is a petrol tanker sometimes connected to the ground by means of a wire before petrol is uploaded?
Most likely, this is to discharge any static electricity that the tanker may have accrued during its journey. Such static can be dangerous because it may cause the petrol to ignite; therefore, the wire 'grounds' the tanker (i.e. it allows the electricity to pass harmlessly into the ground) and removes this threat.
Does the ground run from the battery to the alternator?
Generally the battery ground lead is connected to the engine block and the alternator is bolted to the same block via metal brackets and thus connected electrically to the battery ground.
