I just replaced my AC clutch as the Bearings were toast and the coil was burnt up, but the clutch does not engage when I turn on the A/C. The fuse looks good. Any Ideas. I want to try jumping the compressor. Does it matter which terminals I connect the pos and negative to ?

did you measure the clearance of the clutch with feeler guages? theres a specific gap you need to enforce follow when you install those.
 
i dont know what you mean by "which terminals". i would try to apply power directly to the compressor though with a power probe. or at least use a test light to see if you have power going to the compressor. my guess is you may not have power since you just replaced the clutch (i asssume coil also).
 
I tested the current at the clutch and had no power. I jumped the clutch by connecting it directly to the battery and it started working. I also used a paperclip to jump the switch on the evaporator, that didnt do anything either. whet else am I missing?

i would try to figure out now why you dont have power to your compressor. maybe a critter got in there and started chewing wires, ive seen it a hundred times. maybe check your fuse again. im not sure on fords, but on hondas there may be a couple fuses for the whole A/C system between the under hood fuse box and the under dash box. is the A/C system the only accessories that arent working? it may be a whole circuit thats INOP.
 
The field coil for the clutch was burnt to a crisp, so I could see it blowing a fuse. I checked the fuse in the kick panel labeled in the manual as being for the AC Clutch and the Defroster. It looked fine. Any others I should check? Wiring looked ok as well.
