bathroom wiring

my son in law added 3 new lights to my bathroom last night. He added it into the exsiting wiring from the switch. Now everytime we switch the breaker back on it shoots sparks and flips off so we have no lighting in 3 rooms. We live in a mobile home and I know the entire house needs rewiring but thats not an option right now. Hes checked everything and we cant understand why its shooting fire and wont stay on. AT first it stayed on for a minute till we turned the lights off but when we hit the switch the breaker blew and wont come back on. Its our first electrical project and something we arent real comfortable doing so we are a little nervous. Thanks for ANY help. We are quite desperate at this point. Thanks again

Obviously there is a problem with the new wiring he added.

Exactly how did he connect into the existing bathroom circuit? What wires were located at the switch, and how did he connect to them?

You have the wrong wires connected to the switch. I will try to help yoiu, but you have to tell me exactly how you have the wires connected.

Boy, it seems that a large percentage of the problems we have here involve the words "switch loop" and "impossible" in the answer.

If the switch had a white wire connected to it before he started work (and I suspect it did), then he is attempting the impossible. He cannot wire new lights from the switch. He must wire the new lights by running the cable to the old lights.

If I ever write a book on home wiring, I'm going to cover switch loops on page 1. On page two, I'll explain how to find and reset a GFCI. On page three, I'll explain how backstabs fail. On page four, I'll tell you how to look for the little tabs on the side of receptacles when you replace them. On page five, I'll say what to do about dimming lights. On page six, I'll talk about why you can't connect your receptacle grounding wires to pipes or grounding rods or the neutral. On page seven, I'll tell everybody to spend $6 on the book "Wiring Simplified". If everybody who touched their wiring read those seven pages, we wouldn't have nearly so many posts here.

John,

If you write your own book, why would you want someone to buy somebody else's book?

Won't you try to write a better book than Wiring Simplified (which I will give you is a very good book).
