Here ya go, Mike and Jon. Sorry... between the fading of the sheet before I thought to photograph it a few years ago, and having to downsize the resolution in order to post it here, it may be somewhat hard to read some tags. But print out several copies, for bay door, owner's manual, and service file - be sure to use the slow, high quality selection on your printer in order to maximize readability. You might even want to laminate the one you put in the bay; and it doesn't have to be glued to the door... twisting my neck or standing on my head to read it is no fun anymore

K3 is the condensor fan, Mike; I'll leave it to others here more electrically adept to prognosis the likely cause of the high current draw and burning. Circuit Breakers 15 and 37 (and perhaps 16 according to wiring diagrams) are Jon's entry step - b.t.w. a common entry step issue is the magnetic switch in the door.
But keep in mind that as Jon alluded, my Ventura IV may be different enough from yours that some circuit breakers, connections/buss locations, and relays may be different, so use mine as a general guide and not an absolute. In fact some of the wiring documentation that came factory-included with mine has proven to be off on occasion, as installing technicians fudged on their paper guides for whatever reason.
