Q:

How do you reverse a single-phase motor?

A:

Single phase motors can be reversed by either swapping the starting winding or the running winding around but never both. When both windings are swapped around, the motor still runs in the same direction as it did before.

To determine which winding is which, a multimeter must be used to measure the resistance of each winding. The winding with the higher resistance reading is the starting winding while the winding with the lower resistance reading is the running winding. To determine the resistance of each winding, set the multimeter to read in ohms.

Once the starting winding has been determined, use the motor's wiring diagram to determine which starting winding leads to swap. If the motor does not have a wiring diagram, begin with the starting winding lead that is connected to the capacitor or centrifugal switch. Take the end of the lead that is not attached to the capacitor and attach it to where the second starting winding lead meets with the two running winding leads. Then, take the end of the second starting winding lead that is attached to where it meets with the two running winding leads and attach it to where the first starting winding lead was originally attached to.

    How does a boat work?

    A:

    Boats and other waterborne vessels operate on the principle of buoyancy, or the property of fluid that causes it to exert force at all points on an object. When objects are placed in water, they sink until they displace the equivalent of their weight in water. Boats have a hollow interior and are large enough to reach this goal without being submerged.

    Do golf cart batteries all have to be replaced at the same time?

    A:

    All of a golf cart's batteries do not have to be changed at the same time, but running an old battery with a fresh one will not be as efficient as running all new batteries. Experts advise golf cart owners to replace all batteries if more than one is dead.

    How do you winterize a four-stroke outboard motor?

    A:

    Outboard motor manufacturers recommend professional end-of-season servicing before the motor is stored for winter. Four-stroke outboard motors can be damaged if they are not serviced properly before storage, and failure to do so may also void any warranties.
