A Rotary Electronic Ignition Unit

Forums

Can anyone help with my electronic ignition unit [EIU] for my Rotary IP2? This IP2 was owned by Norton and used as a "Demonstrator". There is a difference in cable colours shown on the Wiring Diagram [WD] and those on the actual EIU. 

The wiring diagram shows;                                                                The EIU has;

Red, 12V going to Ign Unit Relay [IUR] ..............                         BUT no red on EIU /. Does this red simply pass straight through the EIU? If so can I just wire into my ignition switch?

Slate Red and White Slate going to Ignition Retard Unit .............BUT no SR and WS on my EIU

My EIU however does have a Slate and Slate Black which is NOT shown on the WD

All other colours agree.

Sorry about the abbreviations [EIU etc] it saves my little fingers but I hope it is not too confusing [I wrote it and I am confused so ...]

I have tried asking at ANIL, Startright and the Rotary Owners Club but so far no joy and I want to get on with the rebuild.

I presume the bike is younger than the WD, may have been experimented on?

I hope someone can help and prevent me making expensive mistakes.

Many thanks in advance Regards Roger

With the retard box removed you will have two wires coming from the left side of the engine , usually grey and grey with black these are ignition trigger wires . Connect the ignition trigger wires with individual bullet connectors to the two wires of the same colour on the electronic ignition box .

 

So that sorts out the Slate and Slate + Black wires.

Thanks John, why do I not want the retard unit in the circuit?

Because its a failure waiting to happen from water ingress according to Startright, unless you can find a way to seal it properly, in which case keep it as a stable idle is a good thing to have.
