Sears Kenmore Freezer (1995) tries to start, clicks, compressor hums, then stops.
Repeats every half minute or so.

I believe the starter-PTC and/or the run capacitor is broke.

Removed the part (starter+run attached together). It rattles a lot.
So would like to use a Supco hard-start capacitor to see if will maybe fix and at least diagnose if the compressor is bad. If compressor bad, will discard freezer.

The compressor only has 2 prongs; expected to see 3 of them: start, run, overload/common.

The starter-PTC has prong receptors labeled left to right, 5 and 6 (not R and S, or S and R).
starter-PTC has a 3rd receptor labeled 9, but there is no corresponding compressor prong.
And, of course the Supco has 3 wires - but where to attach them?????????

Searched everywhere and no luck.
