My 2021 model has a 12V 60A circuit breaker under the street side bunk.

ii am at a camp site. tomorrow i will look for this.

i did find the fuse but unless the fuse is bad i flip it on and off but didnt seem to solve the DC power problem i. the trailer. i don’t have a meter to test the fuse.

Imelda,

The 60‑amp circuit breaker under the street‑side bunk also supplies power to the jacks in my trailer. Do your jacks work? If they do, then move on to the converter—located under the dinette in my unit—and check the fuses there. If the jacks don’t work, the breaker is most likely the issue.

Dean, jacks do not work. i cannot get the trailer of the truck hitch. i did flip this 60V and it did not fix the problem. i wonder if i can over ride it or maybe it needs to be replaced. 

i am wondering if I can manually lower the hitch  jack so I can at least unhook the trailer from the truck. 

[Dean and Mary]

I should have started by asking whether you have voltage at the batteries, and then whether you have voltage at the input side of the 60‑amp breaker. A voltmeter will help immensely. It could even be something simple—like lithium batteries that were accidentally switched off.

On my trailer, a 4‑gauge cable runs directly from the batteries to the 60‑amp breaker, and that circuit is independent of the heavier‑gauge cable feeding the inverter. I can double‑check in the morning, but I’m fairly sure the wire going to the converter is connected before the 60‑amp breaker, which would mean the breaker isn’t the issue.

I hope this doesn’t add to the confusion. Dean

Electric RV jacks almost always have a manual method for raising and lowering them in the event of dead batteries. The connection point is located on top of the jack, and the trailer includes a tool designed specifically to operate it.

[Imelda]

Dean this is very helpful. unfortunately i left my volt meter that i normally carry in the trailer at home but i will try to manually raise the hitch jack with the hand crank tool and then go into town and buy a cheap voltmeter at an auto shop so I can check the batteries. i have lithium ion batteries. and then check voltages from there. i will check the manual and look for wiring diagram. maybe someone at this camp ground has a voltmeter.

If you have Lithionic batteries, there is a round push button switch on top of each battery. If they energized the push button will have a light on.

Try calling OTT before they close for the weekend. They may help.

Well i broke down and went into town and bought a voltmeter. the 60 A breaker is good. batteries appear to be good. there is a 1A in line fuse after the 60A that i should check. it’s getting really hot in the trailer since no AC but I only have one more day and then home. hoping for cooler weather at home to continue the trouble shooting. 

thanks for the reminder of the manual jack tool. I was beginning to panick but I did find it in the trailer. 😀 I had seen it before but had no idea what it was. so i can lift the jacks to get home  🤞

to be continued.

I was wondering if there is a wiring diagram somewhere. i don’t see it in the manuals

If you have 12VDC at both ends of the breaker, the same breaker that has the 3 big yellow 30A fuses for leveler jacks, the jacks (unless all 3 fuses are blown) and the lighting should work. Something is not adding up. Test again to be sure that +12VDC is on the load end of the breaker, or recheck both sides. Picture below is from our older hull before I changed all that.

Ours had a 40A fuse vs. 60A but yours should be similar. The source side is on the RIGHT in this picture where power comes from the battery. +12VDC there means batteries are working. Power on the LEFT post means the breaker is closed (working). You should also see power when touching any of the screws or the metal of this positive bus.

Where are you connecting your voltmeter to ground? (battery negative) 

If the breaker is bad, you could bypass it until you replace it, since all the loads are fused individually.

i checked the  60A breaker by just checking to see is if i got a really low resistance value across it as i wasn’t exactly sure where i could get a good ground connection but you are right I do need to check the voltage. I am not sure if this 60A breaker is before or after the converter so if it was good or bad that would tell me about the converter. display lights and fan are on the converter so I am not sure if this says it’s good. . fuses are easier to replace than converters/inverters so when i get back home I will run up a ground wire directly from the battery ground terminal and use it to check for DC voltages. thank you for this.
