can someone tell me how to work-out which type of plugs i have? what size they are on my clarke 105 enb?i've just bought a set of clarke arc leads of ebay (these plugs say 35/70 on them)and i want to convert my 105 and my cosmos 150 arc to use the longer earth lead.also convert the live side on my cosmos to use longer live lead.cosmos has no sockets so what do i need ?which would be easier changing the plugs on the new leads to match the ones on the 105 and getting same size plugs and sockets for the cosmos?
