Talk Morgan Forums Morgan Sports Cars Morgan Three Wheeler & Super 3 Start button & speedo not working!! Very Strange

Here is a snapshot of the relevant part of chassis wiring loom.



The shorting plug if no immobiliser fitted is shown bottom right with pinouts used. If you look at the matching cable numbers you can work out the four circuit loops that need to be made (two start and two coil ccts) for the plug to function. As fuse 3 supplies 12v to immobiliser you could check that too.
