HWH hydraulic electrical controls

I spent about4 hrs. diagnosing and repairing my 12V controls for the 12V pump motor.
The slide-out dash switch just caused the motor solenoid to click, no movement. Then suddenly the motor would not shut off.

After letting the smoke out of my motor, I discovered a electromagnetic solenoid switch CAN fail in both the open and closed position.
If your motor fails a new one is available from Northern Hydraulics within 5 days for ~$200.
New solenoids with the mounting bracket on the bottom are no longer available from HWH for my model 610 common-ground system, they are available from Amazon, but they are named "dump trailer solenoids"
I hope this helps someone in the future.

I replaced the two SOLENOIDS on my 22yo DEWALD slide hydraulics because they were sticking in the ON position, tripping the 12vdc Overload/ Breakers near the Battery; later replaced the 12vdc breaker when replacing CHARGE SOLENOIDS, as found it damaged and broke when removed to access the other solenoid by battery. Searching by part#, OEM replacement solenoids were $40-$65/ea at that time (ebay?), but found acceptable SOLENOIDS on Amazon for about $8/each, WITH MINIMAL MODS TO INSTALL.

Solenoid can weld in or jam up. You could wire two in series . Or put manual circuit or battery disconnect inline.
We have solvent distillation unit at work. Contactor welded in for heater . The solvent in vessel may had been to auto ignition point, there's also residual fine aluminum and fatty acids in the mix. If we E-stopped it would have opened vacuum dump valve letting air in to cause a fire and no way to cool it down. I had to pull nine 480v 40amp fuses with insulated/plastic pullers live , pucker up baby. It got two contactors after that. Now it has SCR voltage regulator to maintain constant temp instead banging contactor on and off every couple minutes and safety contactor.

the new style solenoids fit in the same place as the old ones, wire up the same.
appear to be more reliable than the upright style. i have had to replace a new style one in the last 7 or 8 years. i carry a good supply in my truck, because i find this a regular problem. not common, just the few times it has happened. especially the pump relay.
anytime you replace the motor, the relay should be new too.
