How do I fix my pump? You may need to test and replace the motor. Below find step by step instructions on how to test your hydraulic pump motor.
How to test a double post hydraulic pump motor:
1. Ground the housing of the motor using a jump pack or battery.
2. Take the positive directly to one of the posts. The pump will run in one direction.
3. To run the other direction put the 12v to the other post to test the other direction.
4. If you fail to run the motor in either or both directions your motor is bad.
