Found the cable hanging around the alternator. Reason of not having even worst troubles was that its insulation part was longer than the cable itself. So it couldn't touch any part of the engine.
Now it's wrapped up with insulation tape tired it up on the alternator's positive cable. So, it's not moving around.
Do you think there might be any issue with induction with the alternator positive cable?
Tomorrow I will visit an electrician shop for further fix.

Found though another
cable which seems to be manually disconnected (on both ends) for some reason. This might be related to habitation electricities.
