Lost 110v to Some Outlets

Running two portable heaters and anything else may have exceeded the watts number.

I'm sure you are right. Pulling the cover off today to see if there is an internal breaker or fuse.

On some coaches,depending on the inverter model, the 110 does pass through the inverter and that 110 is on a circuit breaker. It is possible to trip a breaker on the inverter and loose partial 110 in the coach.

We have also had GFCIs pop and discover there are lots of things wired "downstream" from them. The one in the galley actually has the outside outlet connected. When the plug for the ice maker is laying in a puddle, guess what happens.

I looked everywhere hoping to find a second panel. No second panel to be found. I assume this is because the ME2012 has branchable breakers and does not need a second panel.

Good luck

THanks for the link, going to look for that fuse now.

FOund the problem.

It is the pop out button circuit breaker on the inverter.

While it makes the definitive click when reset it is not making full contact. If I play with it and get it to hold halfway between in and out it makes contact.

Great to have identified the issue but holy crap batman it looks like a bear of a job to get the inverter out to replace it.

Thanks so much to everyone who took time to reply, I truly appreciate it.

Now one last question, do any of you live close to Middletown, Ohio, if so would uyou be willing to come over and replace while I sip coffee?

Glad you found it. Thanks for the update.
Advice is free. Manual labor will cost ya.

I live in Florida but, if you want to drop the RV off for a few months, I'll replace the breaker and road test !!

I did not know that; thanks for the information. I learn something new on this board everyday. Love it.

Magnum Inverters have NO internal fuses. The only 120 Vac breakers for the inverter circuits are the two breakers you have already found. I think the next step is to take the side access cover off the inverter and check with a volt meter to make sure there is 120 Vac on both OUTPUT 1 and 2 on the terminal block. If there is then there is probably another GFCI you haven't found.

oops I see you found the problem. The breakers are mechanical not thermal so you might try pulling it out all the way again and try pushing it back in. If the breaker is bad you should be able to the remove the inverter top cover without removing the ac or dc wiring (turn the power off of course!) and replace the breaker, it has two push on connectors from the back with enough wire to pull the breaker out a little ways. Check www.magnumenergy.com for the closest Service Center they should stock this part, 60-0020 for the 20A part.

My temporary fix:
Pulled the cover of the inverter to remove circuit breaker 2 (CB2) found the capacitor had pulled away from the circuit board.

The M2012 is a Single In/Dual Out SIDO inverter.

It has a single feed of 120 vac, 30 amp. This single feed powers circuits 1 and 2.

I pulled the feed of the bus bar for circuit 2 and tied it to new wire (#12), feed that wire out of the inverter case to a new box containing a 20 amp breaker. Then tied in to the bus bar at the 120 vac 30 amp feed with new wire (#10) and feed that back out of the inverter in to the box and to the 20 amp breaker.

THis allows me to bypass the bad breaker until I can find and order one. The capacitor being loose did not effect power supply. I assume it's there to clean up the power coming in. Will order one and have my electrician buddy solder it to the circuit board.

If I can't find the repair parts it will be my excuse to order a pure sine wave inverter, the ME2012 is a modified since wave inverter.

The real shame is I rarely use the inverter, if it wasn't tied in to battery charging I'd do away with it.

Anyone see a problem with this temporary fix????????

Wish I had read your post a couple hours ago. You have no idea how hard it was to see the part number on that particular breaker. It's just thick enough that you can't pull it with out dropping the circuit board. My trifocals needed another setting.

Just left Fort Lauderdale last week. Visiting family. Had such a great time we are thinking of buying a lot in FL.
