A/C Compressor coil burnt up?

Travis,

I measured high resistance across the terminals of the run capacitor.


So I removed the plastic cover to gain access to the compressor
terminals. A different story here. C-S is 4.6 ohms, C-R is 2.5 ohms,
S-R is 2.2 ohms but sometimes 6 ohms (these may be a little mixed up as
I did the measurement in the dark using a flashlight and inspection
mirror to place the alligators on the terminals...)

I'm going to try to replace the 35 uF 440VAC run capacitor, its
terminals are quite rusty. I thought about sanding the terminals but
as long as I am this far in I might as well replace it.

I removed the leads and got a low reading from the capacitor contact to
the compressor so I think the wire is ok, doesn't feel brittle and no
charring of the insulation)

Thanks for the idea!
