Primarily when there is movement inside the coach. I have however also heard it when opening the personnel door on the garage I store it in or have even leaned against it and have heard it.

More jack misery

Today I was using the EQ Sys PUBLISHED procedure to bleed air from the hydraulic system. After three complete cycles the pump no longer runs when pressing the buttons.

I've tested the voltage downstream from the solenoid and have a good solid 13.5 volts going directly to the motor itself when a button is pressed.

I believe someone else here burned up the pump motor doing this, even though EQ Sys says it's perfectly OK to do it, IF you wait about 20 minutes between each cycle (which I did).

I'm now afraid I may have cooked my pump motor as well. Anyone know of an after market source for JUST the motor. I hear EQ Sys gets around $700 for theirs.

Boowho??

Yes there are aftermarket motors and at $700 you are getting taken by at least $300 you do not have to replace the pump and motor you can replace just the motor. there are just a handfull of manufacturers that make the dc power units so look and see if you can get any name and numbers off of the power unit. I will pm you a name and number of a place in Illinois that specializes in replacement motors not sure if they sell direct to the public or not but it is worth a try.

boo,
I believe that it was Superchief that burned out his pump. Do a search and I sure you will find it.

Thanks guys..... I'll report back what I find. If I AM indeed the second user to burn up a motor using a procedure provided by Eq Sys, then that's a pretty bad situation.

Now I just gotta find the manufacturer info on the motor itself.

And I think it WAS Superchief who mentioned the $700 figure. Obviously, I agree that amount would be a real rip-off. IMHO, $100-200 would be more realistic.

Check the pump specs to see if it has over temp protection that you may have triggered.

Good thought, but it's now been several hours since it quit working so It should have auto-reset, I'd think.

Still, I'll check it. Thanks

I had the popping since new. Usually woke me up during the night.
I added a quart of fluid, ran the jacks up and down, and the slides in an out a couple times. Was early in a 3 month trip during August.
It may still do it occasionally, but I hardly ever notice it since then.

Nothing special, just the specified fluid.
With all the jacks up and slides in, I was able to add one quart to bring it up to the upper full line.

I think it was a little low initially, but not under the 'minimum' line.

THere are 2 molded lines on my tank. I assume the lower one is the minimum. It was just above that line when I started.
I filled it up to the upper line with all the jacks up and slides in.
