Thanks for your detailed comment.
On the right side you can see the mirror motor, and on the left side is the shutter motor, that you can't see. Only the gear is vissable.
Downunder the red/black wires are vissible, and the connector dissapears behind the yellow tape.
Measuring on the ground from the batterie is possible, but i think it doesn't make any sence, because i wanted the know what power the motors need, and in my opinion can be achived with direct measurement at the motor.
In several documents i read so far, they are talking about a 'phase sensor from the shutter cocking unit'.
I have no idea where to find that sensor, tough it sounds logical that the computer from the camera should be informed what the position from the mirror motor is, when the mirror is up , and when the shutter can be opened.
I could imagine something is wrong with that sensor. When the computer tells the mirror motor to start and there is no information comming back that the mirror is up , so the shutter can be opened, this ends in a err99.
I understand you are a electronc man with a lot of experence, and i think you had also different 'attack strategies' by 'attacking' a electronic problem.
Since that sensor thing didn't bring me any further, i tought about checking the power on both motors.
Maybe another forum member is reading with us, and can bring light in darkness.
