I was trying to find why my mother's ac would not work and saw that the compressor would not cut on. I jumped the switch on the accumulator and the clutch did not engage. I then pulled the plug for the power to the clutch and found I had a circuit with my multimeter with the compressor casing. I then checked for a circuit with the engine block and found none.

So I looked behind and found a wire hooked to the side of the block that looked like it used to reach the compressor and had the eye shear off. I did not see any ground wire from the compressor. Where on the compressor did the ground hook up?

I might just find a useful bolt and make a new ground wire, But I would prefer to reuse the original ground location. Anybody know?
