electrical issues

Well done. :slight_smile:

Maybe the odd wire you refer to was part of an alarm system that was stripped out before you got the bike?

it’s very weird,

this metal plate seems attached properly to the tank, doesn’t seems to have been fitted manually, also i notices that the wire has 2 lines ( + and - maybe?) but they both end in this metal plate, while at the other end there is this female spade connector

???
