Compatible Models
We do our best to list all compatible models. Although this may be the part you need, your exact model may not appear below.
- Monarch / Bucher hydraulic power units using 07522
- KTI dump trailer hydraulic systems using 391-2-C
- PJ Trailers and compatible dump-body power units using 190107
- RV leveling and compact hydraulic pump systems only when the same intermittent solenoid is specified
Product Overview
A pump motor that will not run, runs only after tapping the solenoid, or receives control voltage without output to the motor may have burnt contacts. Weak batteries, corroded grounds, remote controls, circuit breakers, cables, and a seized pump motor must be checked under load.
This switch is rated for intermittent hydraulic-pump operation, not continuous motor duty. Holding it energized beyond the system cycle can overheat the coil and contacts.
Match 12 volts, four terminals, 100-amp intermittent rating, curved mounting base, stud sizes, coil wiring, and original reference. Confirm the motor current is within the power-unit specification.
Key Features & Performance
- 12-volt coil with four-terminal circuit

Compatibility Notice
Northline Parts does its best to list all known compatible models, but the correct part may fit an application that is not shown above. Model year, production date, serial number, engine or equipment specification, installed options, and previous repairs can change fitment. Match the original part, reference number, dimensions, connectors, mounting points, and product photos before purchase.
Frequently Asked Questions
Q: Can I use this as a continuous-duty battery contactor? A: No. It is an intermittent-duty hydraulic pump solenoid.
Q: Why does the solenoid click but the pump not run? A: Battery voltage, cable resistance, bad contacts, motor failure, or a seized pump can all cause that.
Q: Is it safe to work under a raised dump bed? A: Only when it is supported by the approved mechanical safety prop and all stored energy is controlled.
Q: Is this an original-equipment part? A: No. This is a new aftermarket product. Brand names and part numbers are used only to identify compatible applications.
