Hyd. pump and self leving and operating of the slides

[Tow'd hauler]

I have been having an issue of when bringing in the slides (living room) I know the hyd. pump is used and it stops you hear click and push the switch again it starts to move again I know this happens when its cold but the lat few times I'm in a location that its 75 degrees so its not cold also when taking up the jacks they will stop and start up a couple times, any one else having this happen? And what is the issue and can be done to get this working like it did as new

Sorry I can't help you with you self leveling but I was very surprised to see someone here with a Meyers Tow'd. My dad was a Meyers Manx dealer in the sixties. Our Manx was serial number 498. Post some pictures sometime. Good luck with your leveling system. I'm sure someone here will get you fixed up.

The hydraulic system uses a auto-resetting circuit breaker on the power feed. They've been known to weaken over time and require replacement. It should be located close to the hyd. pump. You may want to clean/lubricate the rams on the slide drive and levelers first to see if that helps.

We've been having the same start/ stop problem with the jacks on our 2016 Momentum. It only happens when the jacks are coming up. They always restart but it's annoying. We will check the circuit but the trailer is only seven months old. Any one else seeing the same thing? Thanks!

There have been several threads on this site in the past year, about breakers being tripped. If you do a search, you should find an answer. We had the same problems during the last several months. I replaced the main breaker located near the battery box by the hydraulic pump, which was one about 50 amps. The easiest way to figure out which one it is, would be to disconnect each line until you find which one powers the slides or jacks. On my unit, one breaker powers the pump for both the slides and jacks. I was able to buy a breaker at one of the auto parts stores for about five or six bucks. One the breaker begins to trip it becomes weaker over time. Our unit was about six months old when it began to trip. Have not had an issue, after doing the replacement.

Thanks, gordofuchs! I guess the breaker is the place to start.

I was having the same problem and Tim at the Quartzite rally let us know that is the auto circuit breaker getting weaker, as Dave above noted. Find the Hydraulic pump and follow the red wire back to a junction box. Mine was covered by a plastic type cover. Apparently they are a $6 part to replace.

Why would a circuit breaker get weaker with use? Amperage overrated, excessive amperage, or poorly built. Probably the latter?

It just happens. Believe it or not, you home circuit breakers do the same thing. The difference is you rarely reach that "weak" point. But they do in fact get more sensitive over time.

We had a central GFCI residential breaker in a stick built home that did this. It was tripped maybe 2 or 3 times, and then virtually anything would trip it. It was a Siemens if I remember right - not shoddy - but I had to replace it several times. Those are very sensitive.

 

[offtohavasu]

GFCI breakers are VERY sensitive. And they have to be, that's their general purpose. A lot of time with them, it's an appliance that's failing, but hasn't failed that has something go to ground and it trips. Ok, I now return you to your regularly scheduled post.

 

[RamGunner]

The first I replaced after it was legitimately tripped 2x was so sensitive that waving your hand in front of a connected outlet would trigger it.

 

[Specularius]

What causes the breakers in an RV to become weak in a short time is directly related to Ohm's Law. When the voltage in the battery gets low, and something like the hydraulic pump turns on, the amperage jumps causing the breaker to trip.

 

[GD350M]

This issue presented itself to me yesterday. I might go get me a couple of different breakers to keep as spares.

But when you say change out the 50 amp breaker for the level up system, are you talking about the main 50amp breaker in the unit? The level up breaker that you changed is in the breaker panel or near the hydraulic reservoir?

 

[Specularius]

It may be under a small plastic cover on the divider wall to the pass through storage. Follow the main power wire from the hydraulic pump. It will connect to the breaker. If you are caught in a bad situation,you could always connect both wires to the same terminal on the breaker to get power to the pump to get you out of the bad situation.

Is there a certain brand of "Short Stop breaker" that is recommended?

 

[Dick 641]

They replaced mine at the GD rally last fall an it is still doing it, hope somebody find an answer for this. Going to look for a 60 amp breaker an see if that helps, or maybe a different brand.

When you say, "They", I am assuming that you are making reference to the Lippert team. Since owning my unit, I have tried to stay away from any LCI replacement parts, if possible. You might want to try to locate one from a reliable parts store.

 

[orbiker]

I replaced mind after chatting with a guy on FB. He said Lippert said the the system is supposed to have an 80 A breaker, so that's what I did.

Here is some pics.

I cut the power wire in the middle and mounted the breaker to the wall near the Hyd. pump. (note) There is something very solid in the wall to the right of where I mounted my breaker. I have a 2016 380TH.

I moved the lead from the left side of the old breaker to the power side of the breaker.

orbiker,

I see you have an unfused black wire off of the top post that goes to your breakaway switch just like mine.

If that sucker ever shorts out, there's nothing to limit the current or open the circuit. I fixed mine.
