Sid,
You may need to re-visit the engineers office or maybe your police fit is different.
As I mentioned before -
Go to your machine - BAT ON - Avionic Master 1 & 2 on and AC if it makes you feel better - Voila instant GEN I & II fail.
See for yourself what does and does not function.
Possibly easier than dredging through a manual and it will be instantly type and model specific as results can vary.
