Electric aid.? Ok. This will be long, so please read. At my moms...

Ok. This will be long, so please read. At my moms house she has a chief circuit box, and one that splits off of it. (which I will phone the secondary power box within this post) The seconary power box is for her carport which has lights surrounded by it, and a shed which also has oodles tools and lights in it. Recently, adjectives the power in the shed outside is gone. The carport lights are also do not work. My son go into the carport one day, and flickered a table lamp switch in the carport (turns bad and on the lights) over and over, and you can clearly see the lights flicker every 5 times or so he flips the switch. They will not stay on. We have tried resetting adjectives the breakers, and it didnt help. We devise it might be the breaker that turns on the secondary power box from the most important power box, but then again if it be that, why would the lights flicker like i said early? My mothers husband just died, and she wants these lights on to be safe. Someone please backing
Answers:    Here's my guess: The wire that connects to the breaker which serves the carport is loose at that breaker surrounded by the main box. Simply tighten it beside a screwdriver (with the power off) and that should fix the problem. In fact, while you're at it, tighten adjectives of the screws that connect the wires to the breakers.
My subsequent guess is that the breaker is bad. Replacing it shouldn't be that unyielding to do.
Also, the connection between the breaker and the power pole might be corroded. You will have to verbs the contact points.
It is illegal to play around beside electric wiring if you don't enjoy a electrical fitters licence. Get a tradesman in back you kill yourself.
