Вроде то нашел. 2 кажись оно

I have checked earth continuity on my Multi from the coils and the injectors as I've had an earthing problem. The earths from each definately go back to the ecu (as Derek says) to pin nos.

10 vertical Coil Earth
38 Horizontal Coil Earth
37 Vertical Injector Earth
28 Horizontal Injector Earth

I then checked each of those four components using a light bulb and earth wire temporarily to battery. With the bulb priming on switch-on and then flickering when you press the starter everything in the circuit from components to the ecu is ok. However, and I may be wrong here, it is my understanding that the circuit to each component is a digital impulse circuit and the ecu is programmed to read flow and return which is why seperate earthing of the components won't/doesn't work. I spliced one earth wire to check and it knew 'cos it came up with an error code for an open circuit.
As mine stands at the moment I have no error codes but also no earth continuity at the ecu outlet at the pins listed which leads me to believe that one of the following is at fault

Ecu itself
Neutral Light Switch
Sidestand Switch
Engine Kill Switch

But as is Sod's Law I've broken both my quick release cheap plasticky petrol hose fittings into the tank so even though I've checked/cleaned all the switches I'm not in a position to try it out yet. Frustrating

Whatever has happened has happened over a period of about three months as I began to have starting and tickover problems way before changing the bushes in my starter motor. (which is why I still think there's an earth problem somewhere and it's not the ecu)

Does anyone know of a place where you can take just the ecu to have it checked as that will be my last resort as it is the most expensive ?

Also don't believe the worksop manual for wire direction and colours. It's wrong in a lot of places and this threw me out for about two weeks until Derek said don't trust it. The diagram shows the actual brown/white positive feed to injectors and coils as the earth !

I've bought a second-hand Firestorm to tide me over as I was getting withdrawal symtom
