Issues with 12volt system

spawnman · 08-15-2016, 03:43 PM

Have a 2013 36CKTS. After being plugged into shore power for over 24 hours. I disconnected the shore power and went to raise the landing gear and the Lippert control showed low voltage. It should be fully charged. I hooked power to the truck and could raise the front landing gear. When we arrived at campground, the Lippert controller was reading 12.4v not hooked to truck so it appears they charged while connected to the truck.

I turned off shore power to check the batteries and I have no 12v power to anything inside the trailer. I checked all the fuses in the kitchen area under the cabinet, and all the fuses in the front storage area that I could find and all tested good. I also checked behind the battery cut off switch and it looks fine.

Are there any other fuses that I should be checking such as an in-line fuse or something else that would prevent me from having 12v power when there's no shore power?

Thanks
Greg

Many units have resetable circuit breakers near the cut-off switch.

Small button on them that is easy to miss.

A battery can show normal volts without a load and still be bad. Usually the case when it has a bad cell. The only way to accurately test one is to put a load on it while you check the volts. Most chain auto parts stores can quickly test them for you.

A blown fuse or tripped relay will show no display on the Lippert control at all. If the Lippert display said "Low Volts", then the volts are there, just not enough.

Silly question but is the "Battery Disconnect Switch" on?

I'm also assuming you turned the main 50 amp breaker on inside the RV..

It was one of those circuit breakers. Have three in the front storage area, one was tripped. Pushed it and now have 12v power again..

Thanks so much for the help, you guys are the best!!!

Here is a little tidbit on that. The breakers drive the circuits powered by 120v (shore power). The fuses are your 12v side. In your case, your tripped breaker, wasn't allowing the converter to send current to your bat(s). Your trucks 12v system however, is a direct charge to your bat(s), thus you were seeing progress when using that circuit, albeit not long enough.
So, just be aware that if you're not seeing total charge, or near it when plugged into shore power after a few hours, check that breaker to make sure your energized. Just sayin'

That's true except those 'breakers' being referred to here (see post #3) are 12 volt devices. They're commonly called ShortStops, but they are technically circuit breakers.
Just didn't want someone to think that these were 120 volt devices.
