Slide 50 Amp Fuse/Breaker

[tonycamacho]

Getting the Monty ready for another trip North of the Border. I retired from skippering yachts so the wife and I are going to try our hand at Work Camping and we have our first Workamper position waiting for us in Florida.

When operating my slide to open or close it stops, I release the switch wait a second then depress the switch again, it will work for a few seconds then shut down again. I continue this process until the slide is completly close or open. I suspect that the 50 AMP auto reset breaker which is wired to the slide pump motor is failing. I have bypassed this breaker and slide works normally; no overheating of the wires or of the pump was noted to indicate a short. Has anyone ever experienced similar problem and where can I locate a spare breaker. I have not been able to find anything close to this breaker in Mexico.

Very common problem that has been discussed here a lot. A search for slide stall or slide problem should give you lots of reading about solving the problem. Some have simply replaced the old one with a new 50 amp breaker and solved the problem. Some have installed two in parallel to share the load, some have installed a single higher amp breaker.
You can get them at RV stores and auto parts stores in the states. Don't know about in Mexico.

I did this and my problem went away. You could use 2 40 Amp breakers instead of the 50's if you want to.

[Art-n-Marge]

Two 40 amps breakers may be easier to find than two 50s. You'll also find that two of either of those is less cost than a single 80 or 100, which is why so many of us go the dual 40 route.

Just so you know there are several other things that can cause the stress for the circuit breakers. Here's the list:

1. Weak battery. If the voltage is low on the battery because it's weak this will cause an increase in current and caust the circuit break to reset. If your battery(ies) is(are) weak plug into shore power or your TV to gain more "juice".

2. Reservoir is low - make sure the fluid is within 1/2" from the top of the reservoir. You might make a mark with a permanent marker to make this easier to check next time. Use the least-expensive ATF Type A (not Type F) or Mercon/Dextron ATF for keeping the reservoir full. If you are constantly refilling this, you might have a fluid leak (separate problem).

3. Not level and stabilized - the rig must be level and the stabilizers down to minimize any extra movement which can cause more stress on the system. Don't forget to chock the tires to prevent as much movement as possible.

If these are all good, it's probably the circuit breakers. The fix came from the slide company because they found that Keystone and others might be using too low of values for the breakers with as many slides are installed. While the slideout systems are specificed to run from 40 amp to 100 amp, some units need higher values and we found that in Montys is best to use more than 80 amps in the circuit.

Here's a picture of my fix. I constructed the dual shunts shown in Trailer Trash 2's post. You can see them in my picture of my fix:



Don't pay too much attention to the color of the wires. The red wire way on the left goes to the slideout motor and the two wires way on the right go to the POSitive of battery. There are two wires there because the other wire goes to the landing gear motor. Note the two circuit breaks interconnected with 4" of #6 wire shunts and shrink wrapped - AUX to AUX on the bottom and POS to POS on the top.

If you need any more documentation or pictures let us know.

The couple of times I have experienced this, I determined that the problem was low battery power (Art's point one)...it has never happended while plugged into park power.

[tonycamacho]

I did the checks to the batteries, oil levels and the Monty is plugged in sitting level under the cover of my RV & Boat storage unit. Thanks for the inputs, problem has to be the breaker and I will copy Art's fix.

[Art-n-Marge]

Thanks Tony. I want to make sure credit and thanks goes to the MOCers before me (and there's a bunch) that have passed down this fix. I was so happy about solving this irritating problem I pass it on as freely as I can along with the other things I learned. There are many to name. Plus, they also provided me with the .pdf files documenting all this from Lippert.

If you'd like the files send me a note with your email.

Here is another solution to your problem. This is what I used.

7.3 Thanks, I just ordered one on ebay.

[CORattler]

I had mine replaced with a 80 amp under warranty as noted in the Lippert 0058 advisory. I did find, however, that the slide would still hesitate with a partially discharged battery (and I have a 2 6volt system).

[oldelmer1]

After reading the info on the above breaker from EBAY, it says:

80A CIRCUIT BREAKER FOR 12V DC CAR A/V SYSTEM
For car audio/vedio system overlord protection
No fuse change troubel & headache
Easy to operate with manual reset arm
Manual open circuit push button
Max amperage : 80 A

It sounds like its a manual reset, not auto reset.

Just an FYI!!!

[pineranch]

I can do manual. In fact I think it's a plus since it may drive me to investigate the root cause of the tripped breaker.

You are correct it is a manual reset, but I have never had a problem with it tripping.

my 2006 3000RK is doing same with slides. Have plugged
into 110 power still same. I have a flat fuse in a
flat box. nothing like you guys discribed. am I looking
in wrong area by battery box.

[pineranch]

Anyone know what happened to the lippert 0058 advisory that someone spoke of earlier?

norm - don't know about your 3000RK, but many including mine are located on the bulkhead behind the battery and below the pump. Here is a picture of mine. The two red things are the breakers, the one on the left is for the slide pump. There is also a fuse in the flat case in the red wire that is for the front legs.

Norm, I have the same unit you have, 06 3000rk. The picture BB_TX provided is exactly what mine looks like. When I had the auto reset breaker go bad I replaced it with the same that was in it, I think 50amp, and have not had a problem since. With only two slides on our model I don't think they are as prone to failure as the 5'ers with 3 and 4 slides as the pump doesn't run as long with each sit up and tear down. Jim

Went down to the local auto parts bought two 40 amp breakers assembled them on a metal plate, screwed the plate down in the same location behind the batteries and
wired them as shown in the above pictures. "It's magic the problem is gone". MOC thanks for the help.

thank you very much, now I see what going on. Did you replace both fuses or
just the one on the left in the picture. once again thank you
