If both these are true, your compressor is probably OK. Could be bad mechanically, but that's less common than a burnout. Hope that's the case!
ok, C to S, C to R both 0
C to shell, 1 so no connection from case to C.
I made sure by touching both to case and getting 0 then moving one to C and still nothing. So bad cap, right?
