no power inside 94 mallard

[miwei]

(my apologies in advance I simply can't just 'cut to the chase' it doesn't make sense to me lol so I'll channel my hubs then ask the way I feel comfortable)
Having recently purchased our first travel trailer a 1994 fleetwood mallard 29' it's on a permanent campsite under a 40' shed.
Hub's version: I left two lights, and shutdown power supply. today I plugged in the power and flipped the breakers one for the shed & patio, the other for the TT. lights outside work inside nothing. no idea where the fuse box power converter is located.

My meandering version:
the issue is this: I've tried to gather schematics to better help hubs but I can't find any. it seems he decided to leave the two lights above the sofa on, so that when he came back he would have two lights on when he turned the power on (i think he blew a fuse or tripped a breaker).
I'm thinking he's either blown a fuse or tripped the gfic-he finally located in the bathroom-he said it wasn't pushed out. he's not the most patient man when it comes to things like making certain to keep shoreline circuit breakers off before plugging in the power cord and flipping said circuit breakers several times, hoping against hope that it actually works to turn inside lights on.

if it's not a blown fuse or circuit breaker what might be the cause?

I'm learning that he didn't put a pressure regulator on the outside faucet either last week before hooking up the white hose to the TT water intake (he bought one today and has it attached to the intake piece on the TT, shouldn't it be at the faucet end?), causing the cap to blow off the kitchen faucet, and a leak at the toilet.
if anyone has advice or a website where I might find a manual for the mallard i'd greatly appreciate it. thanks Mi

If it does, that would be the most likely suspect.
Assuming there is a battery involved: Then have the battery load tested. (If you're new at this, label the battery cables to be sure they go back in the right place, and note the + positive / - negative positions on the battery)
While the battery is out, turn on shore power and check lighting.
Note: There are a few older converters that require a battery being installed, in order to power the lights. If your's is one of them, you'll need to wait until you have a known good battery.

thank you for your reply.

no battery, someone stole the one the previous owner had installed.

what size battery would he need to buy?

now he's saying it may be the power supply that connects the Trailer to the pwerpole is this something that he could swap out himself? or does a professional need to do it?

As for the regulator, if it's at the faucet end it helps protect the hose from bursting too, and not just the trailer.

If it does, that would be the most likely suspect.

Assuming there is a battery involved:

When hub turned off shore power and left some interior lights on, those lights drained (possibly shorted) the battery.

A dead or shorted battery will draw more power than your converter is capable of supplying. There's nothing left to power any lights. All breakers and fuses could be good, with lights not working. If battery is still good, the converter will take a very long time to recharge it.

Steps I would take:

Turn off shore power, remove the battery, and put it on a charger for 24 - 48 hours. Then have the battery load tested. (If you're new at this, label the battery cables to be sure they go back in the right place, and note the + positive / - negative positions on the battery)

While the battery is out, turn on shore power and check lighting.

Your converter will look something like this.

The lights are most likely 12Volt DC. (The GFCI outlets are 120VAC) If shore power is good, Check bulbs, battery and fuse for that DC circuit. Also, make sure the 120v to 12V converter/charger is working. There is a breaker for that.
You won't find any manuals/schematics for the trailer. The only manuals provided with a new trailer is for the appliances.
