Help Needed Identifying Breakers
Can someone please help me identify these breakers? I am trying to chase down a problem with my inverter. After changing batteries, the inverter only responds while on shore power.
MagnaSine model MS2812.

Sorry forgot the photo. Hopefully you can make out the orange arrows. The one in lower left is only reading .04v.

Have you lifted the cover to try the reset button ?

Hate to sound ignorant, but truth is, I am. I can't seem to get the cover off.

Sorry , I just have the picture  , my coach has different circuit breakers , is the cover soft enough to push the reset through the cover?
EDIT: could you post a close-up picture of the circuit breaker , maybe with a manufacturers name and model number, we can get info on it's operation .

The one on the bottom left protects the 12V feed to the chassis battery loads in the front run box. On the right side, the top one protects the 12V feed to your Intellitec distribution and control panel. The second one protects the 12V feed to to the coach battery loads in the front run box. These two are also controlled by the two relays immediately to the right. They are energized and de-energized by the "Salesman switch" by your front door. The third one and the fourth one are connected in parallel and protect the 12V feed to and from your inverter.
And a thank you to Skip. I thought they reset automatically. I didn't realize they had a reset on them. Good to know!

I holler mayday! I would be incredibly careful at this point.
You changed batteries and now have issues???
You may smoke some expensive electronics if not careful.
Please go to the battery compartment and take pictures of all the wiring.
IF you connected things incorrectly you could have 24 volts, 6 volts, or worse reverse voltage.
It sounds like you know how to use a voltmeter.
In any case, do you have 12 volts on either side of that breaker? If not, check the voltage on the large posts of that fat solenoid sitting there. It looks like it supplies the power to that breaker.

I am fairly certain that things are wired correctly at the battery as I took pictures so as not to get confused.
You may not be able to see it in the picture I sent earlier, but the breaker in question is tripped and I cannot reset it.
There is 12v on the Big Boy.
I do have 12v on the in side, but nothing on the breaker itself. The question I have now is this the breaker that controls the input to the inverter when not on shore power?

What is the rating on that breaker. Another close up will help. The inverter can draw a hundred amps easily so I doubt that is the breaker for it. Just can see it well enough.
What you can do for a quick test is to find one of the breakers on the right that is the same or smaller amps and either just use a jumper or swap it out. If there is a short on the output of that breaker the substitute would trip too.
I would like to look up the part number stamped on the breaker.

These are thermal breakers which are self resetting when the overcurrent is removed. Your inverter is probably hard wired to 12 volts through one of these. If it is open because of an overload, it may be warm. I’d try disconnecting the 12volts to the inverter and and let it cool. Then you can check the breaker to see if it has reset. If your inverter is really overloading the breaker, that breaker should open, cool down and reset, and immediately overload and open again. These breakers can get weak over time. I had one that was on the line that fed the engine, lights and instrumentation. It would open up and I’d have to coast to to side of the road and after a couple of minutes everything would come back and I could start up the engine. Replacing that breaker fixed that problem
