Hi, i've been following the site for years, I did post in the newbies bit to say hello... Unfortunately the time has come for me to plea to the surf gods for abit of wisdom... Can anybody tell me what these to things are in the pictures? I have found a snapped wire, and im already working through gearbox issuse. Would be a great help.

Kindest regards
