Williams 285 wiring diagram

[itspaul]

Hi all I wonder if anyone has or knows if there is a wiring diagram available online. ? I’ve had some problems with mine today misfiring and eventually stopping and refusing to start I’ve identified that I have no impulse to the injector on the rear cylinder I’ve had the rail out and checked it’s not the injector just no impulse so I need to try and trace if it’s an electrical break so where.
Thanks.

Which engine ? They were textron mpe750/850 and now rotax.

The textron have comprehensive service manuals online but I don't recall if they have wiring diagrams
