If the top two pins were bent, then it sounds like the bus connector 
was connected one pair of pins too low - this would then short the
-12V directly to ground, which fits with the symptoms you reported!

With some new fuses, and following Dieter's suggestions, hopefully 
you will be up and running OK!

Hi Bakis,

I hope that the cause. I noticed that on one of
the connector's, the highest pins, where bent a 
little to the outside. I remember having trouble
getting it connected! Now, this evening when I 
checked I saw that this connection was indeed
not right and could explain the blown fuses. 
Alas, the suggestions of Dieter you uploaded 
I can't use this evening anymore, cause I have
no right fuses left. So tomorrow evening I will
try it.
No, the volts have been and are the right ones,
no doubt about that.
