Ok. me again.

I went to braingears and looked at the tempmatic schematic. Turns out pin 15 is the positive voltage into the klima. I believe it was overloaded by a bad electrical coil on the ac comp clutch. I measure from pin 87 of Klima to ground, and got 0.07 ohms. I unplugged the 3 pin connector at clutch and it went open, replugged and 0.07 again.

That value sounds like a shorted coil to me, Please correct me if I am wrong. Oooo...you know what, I will go and test my other car, hang on....

EDIT: Yep....the other car was 4.3 ohms. Time to find a coil and a Klima. Learn from my mistake, dont smoke a klima, measure from pin 87 to the battery ground and see if the ohms are Ok. I will try to solder a short wire onto the board and see if it's ok. That thing ought to have a fuse in the top of it like the OVP. Suggestion...Hint, Hint.

PS - How do you get the clutch off the compressor? Can I do it laying underneath the car with the belt off?
