Ignition Module wiring
There are two separate drawings showing the routing which are 74-00-00 page 29 and page 40 in the heavy maintenance manual.
I have been crying laughing at these drawings. :lol:
coil bottom 1/2 is top 3/4
coil bottom 3/4 is top 1/2
coil top 1/2 is bottom 3/4
coil top 3/4 is bottom 1/2
They are both dated 01/02/15 and show completely different routing for the ignition coils and HT routing. :lol:
If you look at the wiring on both plugs they contradict themselves.
Module A circuit HT coil socket is marked up 3/4T instead of 3/4B for both bl and ws wires,
Module B circuit HT coil socket is marked up 3/4B instead of 3/4T for both bl and ws wires.
Module A and B "socket" that connects to the pick up wire "plug" has contradicting wiring connections.
On one diagram it says wire bl/ge from A3/4 pickup connects to wire w/s, and then the diagram next to it says wire bl/ge from A3/4 pick up connects to wire either bl or gr.
The same applies to all 8 pick up wires.
Not good and very confusing on something so simple and important.
This is the only wiring on the engine. Both plugs on the ignition modules are wrong and the layout of the coils is completely different depending on which schematic you use.
Come on Rotax, this is disgusting.
I hope someone has checked the 912is wiring :lol:
