why did my CAS went bad???
I'm installing a S5 TII in my first gen and try to make it run on a Wolf 3D.
I'm using a modified CAS to tell the ECU the engine position and RPM. These modifications are on the teeth of the cas, not the sensor itself.
The complete CAS (everything from body to sensor itself) was installed per instructions, but I didn't get any RPM readings. After some headscratching I decided to swap the sensor, and use a spare one I had laying around. This did the trick: I got RPM readings.
The engine doesn't seem to get any sparks though, so I was trying to find out why. I played around with the timing, aswell as tried to make sure the CAS was in the right position. I noticed the gap between the teeth and sensor was way to small (the theeth were hitting the sensor) so I tried to adjust a bit. Result: no rpm readings! Gap to large was my first idea, but no way. The sensor just didn't do anything anymore. Changed back to the old one: no result, both are death.
What could cause this? I need to know, because otherwise I'll screw up a few more untill I get the car running
Could it be a slight magnetic field from the screwdriver? I just have no idea.

Do you have any voltage whatsoever at the ECU pins for the CAS (4 pins)? Should have about .8 volts at idle...
There are permanent magnets in the CAS, I wouldn't think you could "de-magnetize" them with a magnetic screwdriver.
Are you saying that the CAS magnetic "pointers" are hitting the pick-up coils in the sensor section of the CAS? I don't quite understand what is hitting what here...

If the gear teeth contacted the magnetic sensors, it means instant death.

Yeah, I guess you never got to play with magnets when you were small and dropped them on the ground.
Contact hIGGI, he's got lots of them.
Hell, he's even got pieces of CAS so he can sell you just the sensors if he wanted to.
