1999 venture 600 self diagnostic system not working

[norwegian]

Hi
My 1999 venture 600 does not do the three flashes at startup. I looked in the shop manual, it says check bulb, wiring harness and cdi magneto (which I assume is the cdi box)
Well it is not the bulb, switched with a working one. The wiring harness looks good as far as I can see, my question is, is it even possible that the cdi box is to blame, everything else works as supposed to. I thought it was more like either it works or it doesn't?

Also it says:
Correct the connection and/or
replace the rectifier/regulator.
Which rectifier/regulator is it?

only one i am aware of is the one for the battery.

I checked for continuity all through the harness. And the bulb works too, I have no idea now.
