have one of these in the yard with a the big ends gone and a possible cat problem ,on older models like this their is a ignition module and a crank sensor so it has to be one or the other ,the module isnt possible to test as such with right gear but the sensor is ,so disconnect the plug connector and rig up the multimeter across the wires from the sensor and then crank engine ,set multimeter to 10v and see if it produces a voltage when cranking engine if no voltage change it ,the module can be tested as well but on the other end of same connector ,connect an old bulb in a holder and then find the earth side of the two wires with the meter then run a bit of wire from this to earth then the 12v through bulb and touch teh other connection and with the centre lead out of didtributor and hold it close to engine touch the bulb wire to the connection and as you touch the connection it should spasrk if the module is working .
