Hydraulic sytem not working, tripping breaker

[stylinstephy]

When we try to do the slides OR the leveling jacks the Hydraulic pump surges, the slides or the jacks move a little then the breaker trips. We have checked the power supply and fluid levels. What can we do or is the pump shot? where can I find a replacement for the Lippert model # 643331?

Having MUCH difficulty even when trying to chat with the Lippert Company. Please help.

Thank you

Fund out it is the pump motor...now if some one can get one cheaper than Lippert Components, Inc Shopping Cart

Thanks!

What do you mean "checked to the power supply"? The slides and jacks run off the 12 volt battery. Have you checked the battery voltage. A low battery will cause excessive current draw and trip the breaker. Remember also, not the starting battery for the engine, but the coach battery or batteries.

That is all fine there is plenty of Juice from the 12V...the motor turns a few times then trips the breaker...

You need a meter, measure battery voltage with no load, should 12 volts or more. Now with the meter still on the battery, try the jacks, or the slides, not both, and watch the meter. Should still be 12 volts. Now connect the meter to the motor, and check voltage while trying to move the jacks OR the slides. Should be over 12 volts. Any reading of 10 volts or less is too low. If the voltage is good, next would be to remove the motor from the pump, and see if it will run. Run for a few minutes, and see if it gets hot. Depending on what you find here is where you go next.

Never assume voltage is good. You must have a meter. Could be corroded cable, bad relay, number of things.

It is down to the motor now....we disconnected the motor from the pump and it truns a few times them "CLICK" The breaker trips, the power "voltage" is good....we now believe it is the motor...looking to get it inspected...hopefully will not have to buy a new one....Thank you all for your help!

Glad you were able to run it down. Motor is cheaper and a lot easier to replace than the pump. Might have a local electric motor shop look at it, just a thought.
