Approach each situation using the following precautions:
•
Understand the problem.
•
Check the symptoms to determine probable cause.
•
Take appropriate action to fix the problem.
Once the repairs are completed, test to see if the equipment is functioning normally.
If not, look for other probable causes and take corrective action until the system is
returned to service.
Safety Precautions
Nothing is more important than safety. The simple rule of safety is that if you think
safety is for the other person; let the job be, too. Keep in mind that beside yourself,
you are also responsible for the safety of everyone around you.

Solenoid Troubleshooting Process
Solenoid troubleshooting can be approached in a couple of ways:
1. You can decide to remove the solenoid from the installation and bench test it
first. After making sure the solenoid is working, you can re-install the solenoid
and test it on the application.
OR
2. You can test the solenoid while still installed on the application and remove it for
bench testing only after eliminating other possible sources of trouble.
