So, you've got your hydraulic dump trailer out on a job site. It's miserably hot, you've got 5 Tons of mulch, trash, shrubs or horse "business" to unload, spread and then go back for more, and you've got 5 more hours to get it done. You go to raise the dump and "Click"... nothing happens. This might be a good time to reflect on your spiritual side. Luckily, a 12VDC hydraulic unit aren't the most complex systems in the world and they are quite easy to troubleshoot. Here is a list of things to check on your dump trailer hydraulic system before you blow a gasket. And if all else fails, give me a call @ 888-898-5031.
- Make sure battery is fully charged. (no-brainer, but I had to put it first)
- Check ground wire (usually attached to frame). The unit will operate but not perform to its full capability if not properly grounded.
- Make sure reservoir is at least ¾ full of oil.
- Check the solenoid valves on top of unit. When energized, solenoid will magnetize, grabbing metal object if placed inside (such as a screwdriver). Remove to test. If solenoid does not magnetize, replace.
- Check amperage (230A draw under Full-Load)
- Check voltage (at least 10VDC)
- Replace battery if the proper amp / volts cannot be obtained.
- Make sure solenoid nuts are not too tight. (approx. 3-5 ft/lbs)
- Make sure solenoid valve(s) are not over-tightened. (approx. 30 ft/lbs )
