Both the high voltage wires of *1 and *2 should be checked to make sure that the wire of spark piston is connecting. If sparks come out when EST plug(wire 4) is being pull off, that means the output voltage of signal picking coil is too low to make EST work. If *3 has sparks, that means the problem is in electricity distributor and spark distributor. When the *4 is in normal condition, there should be battery voltage on both terminals c and + of igniting module, and the voltage is tend to be low, that mean there are breaks or resistance value is too high between distributor and igniting coil or switch.
