Thanks for the help. I lke that website but for some reason i can't get any other PDF's it offers. All are broken links.

OK so here is the latest. I performed the tests in the order that they are outlined in the PDF you helped me get. The #10 pin goes to ground as it should when the CCU tells it to and not when on "ECON". There is power from the #5 as well. Here's the rub: when I bridge the #5 and #7 still no compressor. It looks like the compressor clutch is done. None of the 3 pins on the plug on top if the compressor continue to ground. Looks like a new compressor will fix this part of the issue. I tested the plug going into the compressor and one gets batt. voltage with the 5 and 7 bridged. Here's the next rub: If I put back in the Klima and turn on the AC I get no voltage to the compressor. It looks like I have two things wrong here. My low pressure switch works fine and there is enough in the system so it's on.

There is another un-used pressure switch on the dryer. Normal?

Last question, how does the compressor start up if the speed sensor tells it not to if it does not match engine speed? Is there a "start up" circuit in the KLIMA?

Thanks,
