Bob Hobden. Guest. Mar 14, 2005. #1. A neighbour is driving his 300tdi Disco in early hours of morning when it. stops, engine cuts out, he tries to restart but engine won't turn over. Battery has been on it's last legs for a while so suspects that may be why. it won't restart/turn over. These units are prone to soldered joint failure which give the symptoms you describe. The spider has three functions - Fuel cut-off switch, starter motor, and alarm. Failure of the spider is so common that Land Rover sell a bypass plug that retains the alarm but bypasses the starter and fuel cut-off part of the system.
