Example:- 6 cylinder engine six or three coils (wasted spark) with a firing order 1, 5, 3, 6, 2, 4.
SM4 Ign O/P sequence 1 2 3
CDI Trigger I/P sequence 1 2 3
Ignition coil number 1 & 6 5 & 2 3 & 4
CDI only has two –ve coil outputs and these are wired to the appropriate ignition coil matching
+ve Coil outputs.
Trigger ground on the CDI is not used.
Note:
The –ve and +ve coil wires should be twisted and keep away from any wires relating to the
Cylinder Pulse and Reference Pulse trigger wires.
CDI ground wires must be twisted and keep short (max 150mm – 6 inch) and grounded
near the CDI. Do not share CDI ground with SM4 ground.
