HI Finn

The aircraft just hours before testing the coils. So all is connected =
and functioning.
Why did the injector diag work and not the coil diag.=20
I can remember years ago using the coil diag to test the coils.
Logically - options are:
	1. Tracy changed the sequence for ignition diagnostic. (so its =
no longer mode 8 - push store)
	2. Manual is incorrect and requires Cold Start (But I tried that =
option)
	3. The mode select switch is faulty.
	4. All coils or fuses for trailing and leading coils have all =
failed simultaneously!!! (Not going to happen)

Cheers
Steve
