Trouble shooting motor problems

The authors highlight the most common causes of motor troubles. These causes account for the majority of problems. The key to successful trouble shooting is to identify and analyze all the possible causes and then eliminate each one either by testing or calculations until the problem is properly identified. This method helps the trouble shooter avoid jumping to conclusions and making modifications to components that are not at fault. Because a component does not perform properly, does not necessarily mean that it is at fault. Other environmental factors may be causing the failure and the failures will continue until the environmental factor is corrected.<<ETX>>
