How To Test A Solenoid On A Dump Trailer

Testing a solenoid on a dump trailer is a fairly simple process. The solenoid is the component that activates the hydraulic cylinder that raises and lowers the trailer bed. To test it, first make sure that the battery is fully charged and that there is no power loss between the battery and the solenoid. With the battery disconnected, use a continuity tester to check for continuity between the two terminals on the solenoid. If there is continuity, the solenoid is

How To Test A Solenoid On A Dump Trailer

The following is a procedure for how to test a solenoid on a dump trailer: 1. Disconnect the battery cables from the battery. 2. Remove the cover from the solenoid. 3. Remove the two screws that hold the solenoid in place. 4. Carefully pull the solenoid out of the housing. 5. Test the solenoid by connecting jumper cables to the battery terminals and then touching the

  • Check the wiring harness for damage
  • Jumper battery to solenoid and try to open
  • Check the solenoid for continuity with a voltmeter
  • Check the fuse box for a blown fuse

below -Test the solenoid by applying 12 volts to it. If it doesn’t work, then you may have a bad solenoid. -If the solenoid is working, test the trailer brakes by using a trailer brake controller.

Frequently Asked Questions

How Do You Bypass A Dump Trailer Solenoid?

To bypass a dump trailer solenoid, you can either clip the power wire to the solenoid or remove the fuse.

How Do You Test A Solenoid On A Dump Trailer?

Testing a solenoid on a dump trailer is relatively easy. First, make sure the trailer is disconnected from the towing vehicle and that the battery is disconnected from the trailer. Second, remove the solenoid cover and disconnect the wiring harness. Next, jumper the two terminals on the solenoid with a piece of wire. Finally, reconnect the battery and turn on the ignition switch. The solenoid should click and the dump bed should raise. If it doesn’t, then there is likely a problem with the solenoid.

Why Is My Dump Trailer Not Lifting?

There could be a number of reasons why your dump trailer is not lifting. It could be that the hydraulic fluid is not at the correct level, there is an issue with the pump, or the valve is not working properly. It is also possible that there is something blocking the trailer from lifting up.


To test a solenoid on a dump trailer, one should check the voltage at the terminals and make sure that there is continuity between the terminals and the coil. One can also test the solenoid by applying power and seeing if it pulls in.
