5. Repeat Step 4 for contacts B and E and for contacts C and F.
6. Place test leads on contactor coil terminal as shown in left side view.
7. Check resistance.
8. If resistance is not approximately 390 (+/- 40) ohms, remove MOV and recheck coil resistance. If
resistance is now approximately 390 (+/-40) ohms, replace MOV, otherwise replace contactor.
