One of my electrical outlets stopped working. It's right by the sink and is a GFCI outlet (Ground Fault Circuit Interruptor). This prevents inadvertent shocks and shorting if an electrical appliance got wet, among other things. On these outlets there's a Test and Reset button, and neither of these were responsive. I "naturally" "assumed" that it is went bad because this RV is 20 years old so went ahead and got a new one to replace it. At this stage nothing else odd or weird was happening.
There were five wires attached, two for "main" power, coming from the RV power supply. Then two more were for something which had power supplied from this outlet, and thus protected by the GFCI, and then a ground wire. It is also important to keep track of which wires go where. These outlets are typically always the same in where the wires connect (load and line), but there are small fluctuations here and there.

In this picture, to the right, can be seen the black drywall screws which hold the outlet in place. Think they used these as the ones supplied were too short (tried those myself).

Now, to the point of me being clueless..
After all this work the electrical outlet still didn't work. Was scratching head trying to figure it out but to no avail.. Then a light sparked someplace and went to hunt down the circuit breakers. They're right under the fridge, where the power supply is, and sure enough, one of them was tripped.
Now, something else happened after flipped the circuit breaker.. Heard buzzing again. This confused me as it's been awfully quiet (not complaining) by the refrigerator. It turns out that the buzzing is from the battery charger, so it seems like the part that charges the battery is fed from the GFCI outlet by the sink. Makes sense now that I know about it.
To verify, manually tripped the outlet and checked the "house battery" voltage, and sure enough, it was very very low. Now it explains why the lights were dimming and the exhaust fans weren't operating at full speed.. OOOPS.
