Electrical Help for Newbie Micro Minnie FLX

Micro Minnie FLX

Why would:

Slide make a quick noise, but not move
Tongue jack not move
Stabilizer not move

I can't answer most of your questions but the tongue jack is usually connected to the battery through a fuse. Do you have a multimeter (voltmeter) and have you checked the battery voltage at the battery?

[creativepart]

On the standard Micro Minnie, there is a resettable fuse between the battery and the travel trailer. It is located on the A frame or under the leading edge of the trailer. It can pop and it disables everything on the TT including the Jacks, slides, stabilizers. When this happens folks just push the button on the fuse (a red colored block with two raised dimples) to restore electricity.

Here is a post from another thread here that shows the photo of the fuse.

But I have no idea if this applies to the FLX version of the Micro Minnie or not. So, this may not be applicable to your situation.

[CampinInCO]

Yeah, I don't think the FLX has that. So odd. About the only thing I can think of is battery.

I also do not seem to be charging battery.

Ask the Lithionics engineer, username "electric" here for specific help. Here's a link to his help thread:

How do you know the FLX does not have that pushbutton breaker that creativepart mentioned? Have you looked?

[creativepart]

I would not be surprised that the FLX does not have that fuse. It's a totally different battery setup. Perhaps member, "Electric" will know this answer as I suggested.

If you ever come across a drawing of the FLX DC circuitry please post it here. I would like to save a copy. Thanks

There is a breaker, check my post here #171

That should reset your charging, it did for me.

For slideout controller, check your controller, mine blew up:


The battery does power the tongue jack and stabilizers, when my power system failed, none of that would work.

[CampinInCO]

The FLX has one relay on the front with a small reser that did the trick. Did not think anything would be up there. It also cause one flashing light on the go power to go solid green vs flashing.

[Downytide]

Flashing = charging
Solid = not charging

Is it beeping?

Congratulations, glad you found it. Suggestion, buy a multimeter and learn how to use it, especially since you have a highly electronic FLX.

[SactoSteve]

Yes the FLX definitely has that (undocumented) breaker. It has been the root of several mysterious outages reported on Microminnie and Microminnie FLX, posts. The “always on” components; slide, jack and stabilizers all are powered through this elusive breaker.
An added wrinkle with the FLX is a yet unresolved roll in the solar-on-the-side wiring. As Downytide mentions.
Welcome to the FLX “adventure”

As part of adventure, we discovered more mystery breakers along the system that no one has explanation for, I'm gonna buy the repair shop a digital camera just for this trailer to snap photos as it's pretty much torn apart on the chassis end, they also think one issue it's gonna come up for FLX package is the poor ground, the ground is currently done via self tapping screw.

Wow! Why is it torn apart?

[SactoSteve]

Have a look here
Member Tinglett on another thread of Non FLX Micro Minnies as done great work at documenting what that group has uncovered.
The post in the link above shows where the SOS port connects within the Junction box. This looks reasonable for a Non FLX implementation with out a solar charger i.e., connects directly to ground and battery. It also shows the presence of a load side battery disconnect switch, as well as breakers not present in the FLX configuration. (unless Downytide's tear down is uncovering them?)

Presumably the FLX implementation, given Electrics explanations, should be wired differently. I'd be curious what your "tear down" uncovers.

A couple of posts below the link above is a "nice" picture of the spaghetti in the junction box with explanations of the connections. Massive Kudos to Tinglett and that group ferreting out this level of information!

In short, the power system failed twice that ended up with lots of smoke and almost a fire.

There's no cause yet, but it's being worked on and trying find a solution to this.

@SactoSteve , so the repair shop believes that FLX package is built on the standard MicroMinnie frame, then seems to be modified along assembly that's not recorded, there are some stuff that baffles WGO as it doesn't show in the drawings.

One thing they discovered is that the AC lines come out of Xantrex and runs directly under the slideout, instead of chassis, which can very very easily get pinched when slide out is closing, they are documenting all this, they are also finding bunch of bad grounds, screws literately gone through the wires so there are bare wires behind the panel where the TV sits.

Ours had to have slide component’s replaced under warranty. It was not going out straight. Another upgrade in components from original.

Low voltage or a dying/dead battery usually causes that kind of problem. Plug in the trailer so the power is coming from the converter. Unless you have dead cells in the battery the power to the battery should still reach a voltage and ampacity level that will make the devices work. There is no way that all three motors have cooked! But it is entirely possible that a connection is loose or there are dead cells in the battery(ies). First and foremost check the connections and the actual voltage state of the battery under no load with a good VOM and the voltage when on charge from the converter.

If there is inadequate resting voltage from the battery(ies) then disconnect them and try with just the trailer plug in and no batteries in the circuit. The inverter/chargers on TT have enough ampacity at 12 volts to run devices they are designed to run the 12 volt system completely independently of the battery if necessary. If this was not the case travel trailers with dead or discharged batteries would be a nightmare with a slide out even in campgrounds with shore power.
