Help solve my mystery? Couple weeks out of warranty

[Vanhollymorgan]

I have a 2014 heartland road warrior 415.... Now 3 weeks out of warranty of course.

Here is the mystery. This just started Friday night.
I was pulling my slides in and the last one just stopped. Sounded like the power
Was weak. After 30 seconds I hit the button and the slide came right in.

So I went under the bay , I have the lippert 6 point hydraulic system. At this point I'm running on battery power, my generator is off. The voltage on the LCD screen says 12.8
As I hit the button to retract the legs I watch the voltage on the screen drop all the way
Down to 10.9 and the system cuts off. Wait 25 seconds comes back on and voltage climbs right back up and I get the legs in.

I think ok bad battery. I get home take the battery to autozone, yes battery bad, replace with new deep cycle battery. Test system. Same exact thing happens voltage drops etc.
So in abundance of caution and to test returned new battery bought a another new 27 series battery from camping world. Test same thing happens. Ummm ok.

So plug into shore power. This should boost voltage and everything should work.
Well same thing happens plugged in to shore power. Slides and legs stop on return in journey. Now I'm thinking converter. Take the converter out and have camping world bench test for me and its good 13.7 amps or what ever.

So new battery, converter is good, checked all connections are tight, no shorts. So I think the mini buss fuses in the bay near the generator ( look like grey Legos 2 poles almost) replace the ones that go from
Battery and to the lippert motor.

Same thing happens.

Spend all day with lippert and heartland, no ideas.

My hydraulic fluid was a little low, so they suggest filling the tank, AND changing that buss fuss that goes off the motor to battery to a 40 amp. Done.

Next they say to run slides in and out a few times with brakes in between to let motor rest, and purge any air in system. Done.

Ok plug in shore Power slides come in with out stopping but you can tell still drawing power, the only reason they didn't stop is nc of me replacing that 30 to 40 amp buss fuse in the line.

So I leave it plugged into shore power last night to make sure battery was fully charged.
Went out this morning disconnected shore power, ran out slides, auto leveled, running in slides went real low voltage again, then ran in legs , watched on the LCD screen go from 12.8 all the way down to 10.6 and cut off. 20 seconds later comes back on charge goes back up and I can bring legs in.

So all that still in same boat,
New battery, converter good, new or upgrades on buss fuse, hydraulic fluid topped off. Only thing I didn't change out was circuit breakers in main panel inside. But the fuses in there are all good and the fuses on the converter were good.

Anyone have any further ideas I can check?

I put multi meter on everything slide pump motor, fuses battery and everything is pulling what I think it should.

Thanks for any suggestions?

We had the same issue and upgraded our re-settable breaker to 80 amps...never had another problem.

[Vanhollymorgan]

Lippert swears up and down nothing in motor that would do or cause that, my bet was on the auto reset, I was on a three way call with lippert and heartland for an hour and still no idea. Other thing they are both sure of is my warranty ran out three weeks ago. Heartland keeps going back to battery, lippert says its the 50amp mini fuse inline.

I've replaced that though.

They both agree the voltage should not be dropping on the LCD and my multi meter as the slides and legs come in.

There is very little drop as they go out.

I hooked truck up with 7 way and turned on so that had the voltage at 13.5 dropped to 11.2 and cut off.

Shore power close to same way.

Battery only went from 12.7 to 10.6 and shut off.

I put multimeter on battery and on the pump both and noticed the same drop as it was running. I think it's the motor it just seems to be drawing to much power. But lippert says only fuse or reset is inline that I've replaced.

Check the wire size from the battery to the hydraulic pump...it may not be large enough to carry the load. Also check the wiring to the switch. Does the switch operate a relay, then the relay to the pump or does the switch connect directly to the pump? I would make sure the switch operates a relay, then have adequate sized wire from the relay to the pump. JMHO.

Had similar problem with my TV. Took to mechanic and it took all day and found the same thing that kcmoedoe indicated. The wires would get hot and would separate, when cool (with-in seconds)reconnected and worked like it was suppose to.

This had been happening for over a year until it finally burned through. No fire just would not start.

Seems like the same problem.

Check the actual wires that are feeding from the battery. Often corrosion occurs inside the casing near the battery. They connections can be tight and you would not be able to see the actual corroded wires. The simplest test is to tug on the wires to see if they move easier than they should, or cut back the first few inches of insulation on the wires to see if there is a bunch of corrosion.

Everyone always assumes it the power going out to the device that is failing, but it could just as easy be the power returning from the device, the negative return.

You need to check this first. Put your jumper cables onto your battery and take the other ends to your pump. Run a short wire from the positive jumper cable to the positive input to your pump. Did that help? Yes? Your failure is in the positive feed. No? Disconnect that short wire from the positive feed and put it on the negative battery cable and connect that to the negative return line on the pump. Did that help? Yes... your problem is in the return wiring and you have perfectly good positive wiring to your pump. No.... Then connect both positive and negative wires to the jumper cables at the same time. That should make it work if the pump is working. If not.. the problem is in the pump motor itself.

Go back to the dealer and even if just out of warrenty a good business practice would be to at least provide the parts to replace. If a breaker, it should not be bad this soon into it's working life.

Start simple. Make certain all your wiring connections to the battery are tight. Could be as straightforward as a loose connection causing a high resistance somewhere. Doesn't take much when you're drawing lots of current.

Also call the manufacturer and request a courtesy warranty extension. Maybe you'll get lucky.

So should I replace the 15 or 20 amp circuit breaker in the main panel inside the coach. Then if its still doing it it can only be the internal circuit breaker on motor?

[blkdodge]

I was thinking the same thing with an internal overload on the motor opening up. Bad part is they are just a thin bi-metal switch and will eventually open and stay open, good part is once that happems you will know where the problem is. I just hope for your sake it doesn't happen when you need to get home.

Auto reset Circuit breaker in motor or external going bad ?

I had a similar problem with my landing gear and it turned out to be a bad circuit breaker. Once I replaced the breaker the problem went away.
