Lubrication system. Figure 11-11.  Electric system. is stored in capacitors of the electronic modules (2). At the  moment of ignition, two each of the four external trigger coils  (3) actuate the discharge of the capacitors via the primary  circuit of the dual ignition coils (4). The firing order is as  follows: 1-4-2-3. The fifth trigger coil (5) is used to provide  the revolution counter signal. 11-9
