Compressor start failure error - short between

From Service Manual 621261, p.33:

1.Check if there is a short between compressor terminals; check IPM voltage (under 13.5V); check for shorts between IPM Pins #1~33.

2.Measure line voltage at the power cord terminal block. Expected: 120 VAC (L1 to neutral) or 208 to 240 VAC between L1 and L2 under load.

3.Inspect the cord strain relief and terminal block screws for signs of arcing or heat discoloration. Loose connections here mimic an intermittent power failure to the control board.
