I have a problem with my oerlikon
Are you sure there is not a spade on the cover itself that the connector goes on, a lot of our old telecoms kit has a floating earth lead to earth the cover even though its mechanically attached.It's connected to the cover along with 4 other earth cables so it Defo earths a component. But I'm pulling my hair out trying to find it so any help would b much appreciated. It's a 206 cito arc oerlikon. Cheers
