I have a problem with my 89 190E 2.6L gas/auto.

The A/C compressor wont come on at all. Heres the story:

Bought the car, pulled the Klima relay, it smelled like burned electronic crap, i put it back on.) I hook up A/C gauges (cant stand that hi side connection port location) vacuum for .5 hour. Charge 2.2 lbs or R134a. Set controls for Sno-Cone and the compressor comes on for maybe 8-10 seconds, then shuts off. I pull the Klima, its still stinks (of course, its the old one) I take one off another 190E i have that smells delightful and I know that one works Hook it up to the subject car and the comp comes on for 8-10 seconds and conks out. I shut it all down and the relay stinks like burned electronic crap (yeah, the good one) So I pull apart the new and old one and see that the tracing on the board from pin 15 to the black side of Diode 1 is toasted. Both of them.
What gives?

I am considering a soldering repair. Can someone aid here. I dont want to burn new relays. PS I have checked the belt tension and it is super with a new belt. When the comp did run, it wasnt noisy.
