I tested the start capacitor and it tested fine but I replaced it anyway. Do not use an extension cord, the motor isn’t getting enough power! Each motor has its own stop and start control as well as a single emergency stop which needs to stop both motors. All motors require an great deal of power at the start cycle which is known as an inrush of power. Testing the motor and capacitor should only be made after the electric motor circuit has been identified and turned OFF and Tagged. Guide to Electric Motor Problems and Motor Capacitors Really, this is also how motors can burn out. A motor that is spinning uses less power. Heavier cars need more energy to push down the road, thus limiting your range on batteries. To safely stop a motor 3. Most of the electric motor failures occur at the start up.
