Car will not start with this cable

Unfortunately, the cable does not work, the engine just shrugs a little and does not start. Hergenommen The old cable, with the large plugs it was difficult draufzubekommen but it has started immediately. Apparently, for an old car from 1985, the cross-sections of the cable is too small, that the cable does not work there. As I said, old cable works with thicker cross section and thick plastic clips, this lead. Real shame because the terminals fit perfectly.
