WARNING: ELECTRICAL HAZARD
 Electricity remains in capacitors even when the power
supply is off. Ensure the capacitors are fully discharged
before trouble shooting.
Turn off the power, let the large capacity electrolytic capacitors discharge
completely, and dismount the IPM. Use a digital tester to measure the resistance
between P and UVWN; UVW and N.
