Morphology
The compound names a lead (wire) used as a jumper (a device that bridges/starts a circuit), so the overall meaning is directly derivable from combining the constituent senses. This noun–noun compositional pattern and the functional logic (a wire for temporary/bridging electrical connection) is cross-linguistically common, making it immediately comprehensible to a B1 learner who knows both words.
Etymology
The noun jumper lead may come from the idea of a short piece of wire that 'jumps' across a gap; jumper refers to a quick 'jump' and lead was once a common word for 'wire'. That's why it means a short, temporary wire used to connect batteries or parts.
