Firing order
The firing order is 1 - 4 - 2 - 3.
Ignition cables
The 8 ignition cables of the spark plug connectors are marked with
number 1 through 4 for cylinder assignment. 2 cables each for the
bottom spark plugs are routed together in a protection hose between
the cylinder heads.
◆ NOTE:
The bottom ignition cables can only be routed into
position without spark plug connector.
The ignition cables are screwed into the dual ignition coil and the spark
plug connector, thus enabling easy replacement.
Consult also the relevant section in the Installation Manual.
Electronic rev counter
On the ignition housing there is an inductive pick-up triggering one each
positive or negative impulse at every turn of the crankshaft. The
optional rev counter is a specially adapted AC device.
