How to Test a Stator Coil

A stator is a group of coils that carry a charge and transfer the charge to the battery in an engine to provide power. The stator is essentially the stationary component in the rotary system and is typically part of an electric motor, electric generator and biological motors. These coils can experience a variety of problems such as melted wiring or short circuits. It is possible to test the stator for these problems with a multimeter.

Instructions

1

Unplug the stator connector, which is located on the left side of the engine, prior to testing it. The stator coil has three yellow wires connected.

2

Touch the negative and positive leads of the multimeter to the connectors on the three yellow wires coming from the stator coil. Make sure you test each individual wire.

3

Read the results from the multimeter. The resistance measurements should be similar for all three wires. Normal results are typically .8 to 2 ohms which is a measure of resistance. If the results are lower or higher, there is a problem and there may be a short or faulty wiring.
