Mystery batteru drainage

[Dabby40]

My Bashan storm has some battery drainage issue I cannot seem to find the reason for. A full charge of my battery takes maybe 5 days then it's dead again. Any parts/areas I need to look at?

Looked at:
Battery - Changed out roached battery when I bought it with a new one that still registers as it should.
Alarm system - Removed this as soon as I bought the bike as I read it drained batteries like butter. I will say there is a weird wire that looks similar to a wall plug on the bike after I removed the alarm system. Will show it in the morning but I never saw this on any other bike I have owned.
Starter relay - Tested and works as it should and cleaned it a bit since it was, like everything on my bike when I got it, covered in sand.
