Cultus 2006 ignition fuse problem

The main fuse, which is for Ignition system and gauges, warning lights etc. melts again and again due to heating. The point where fuse is installed has also melted. I got it checked by electrician, but he was not able to identify any issue.
Can someone please guide how to diagnose the problem?
Attached picture should the position of fuse I am referring to.

Its an old car with lot of alternations over the course of its life. But mainly parking/fog lights are installed only. The fuse melts despite the parking or fog lights are running or not.
