No 12v power

[jjflow1212]

My batteries are at 12v, my ac and microwave work, but none of my 12 volt circuit work. (Lights, water pump, awning, fridge) any ideas?

I have a 2016 RB 180

Look for one or more of these close to the battery and / or the breaker for the converter is tripped in your fuse panel..

I’d measure the output of the converter ... should be over 13 voltsDC... even if battery disconnect is in wrong position converter should work and provide DC power to power center DC bus

Yup. And the reverse polarity fuses

Also run a load test on the battery - if it truly is at 12.0 volts, it's either not getting or not holding much of a charge.

With a 2016 that's 4-5 year old batteries so it's likely new battery time, that's about the lifespan of rv batteries.

That is a whole other issue. It hasnt been working for awhile. I have been using a battery charger in lieu of converter. I found the issue.....silly loose cable....thx for all the suggestions

Glad you found your loose wire.

I don't mean to intrude, but I'd suggest that the condition of your inverter & battery may NOT necessarily be "a whole other issue". Some of the 12V equipment on your trailer may not work properly with missing (or low or dead) batteries. While most things like lights will run off of a battery charger, even on your smaller rig you may find that things don't work well with a heavier load. On heavier rigs (with slides, front jacks, etc.) even an operable converter will not supply adequate power in some circumstances and an operable battery will be required. On all rigs, the battery acts as a large short-term 12V power source for heavy/high current items; the role of the converter is simply to restore the charge on the battery for its next heavy use. So even if you have a 25-30 Amp battery charger hooked up in lieu of your converter, if the battery is dead or dying, you may continue to have 12V power issues.

So, I'd recommend that as your resources permit, fixing your converter then making sure you have at least one good battery might make life easier for you down the road.

HTH!
