Air conditioner doesn't work on genny

[rappja]

2019 RT-31 LE
I started up the genny just to "exercise it" as I hadn't used it for a while. I flipped on the air conditioner breakers at the salon panel but there was no power to it. However, the air conditioner worked on shore power. I opened the cockpit table seat compartment to check the breakers in there. The shore power breaker was on, the A/C breaker was open. I tried again with the breakers visible. The A/C breaker opened as soon as I threw the 2 breakers on the A/C panel in the salon to turn on the air conditioning. So that branch was shorting out somewhere.
One more piece of possibly irrelevant information. The shore power breaker in the compartment in the cockpit is always closed (on) because the test button doesn't work. Probably a faulty breaker, and I know, dangerous if anybody is swimming nearby. I had plans to get a new breaker. Is it possibly these 2 issues are related?
I'd appreciate any advice on how to approach this problem.
Thanks in advance.

Update on this. I tried again today. This time, the breaker for the air conditioner below the cockpit (technically an ELCI breaker by Blueseas Industries) (see pictures above) didn't go off, but the air conditioner still doesn't work on genny [ower. Also, now the test button on the Air conditioner ELCI doesn't work (when pushed, the breaker stays in the on position). As usual with boats, weirder and weirder. I think I need an electrician.

The power from the genset goes directly to the barrel switch. Genset power does not go through those breakers at the stern. The dock power comes from the two 30-amp receptacles and then goes to those two breakers at the stern before heading to the barrel switch. The dock power line does connect with the two green lights at the panel (pre-barrel switch) to show dock power reaching the panel no matter how the barrel switch is set.

Thanks for the answer.
By "barrel switch" do you mean the rotary battery switches?

Open your engine compartment, get down in there with your head below deck level and see if the breaker switch on the genny that is all the way up on the left side , above and to the left of the oil fill, is either tripped or off. Reset it.

Thanks so much! I thought of that yesterday, will be on the boat this weekend to check. Hope that's the problem.
