Confused by wire routing for multiroom use


Hi all:
My folks bought an old house and during a bathroom remodel I was adding a can light. When I pulled out the junction box that housed the old light, the wires came apart and I can't seem to get them back together correctly. I have attached a crude diagram, but will attempt to explain too.

I have a hot line coming from the fuse box, a switch in the wall to control the light I'm putting in, and then 2 lines feeding switches in two other rooms.

Before I pulled out the box, it looked like they had a group of whites pigtailed together with one black, and then the other two blacks pigtailed together and everything worked fine. I've tried all different combinations, but either I trip the fuse or everything works but the switch on the wall.

Can someone look at my picture and tell me how to group the wires to make everything work?

Thanks,
John

EDIT: Forgot to add my two wires from the light, but we will call them 9 (black) and 10 (white).

Do you know what a switch loop is? I suspect you had one in the original configuration, for the bathroom.

I'm confused when you say the additional lines were feeding switches. Are you certain? Maybe they are going to lights first, then switches.

Connect 5 3 1 8. Connect 6 4 2 10. Connect 7 9. Place black tape on 8.

If 1 2 3 & 4 truly go to switches then this is a wrong solution.

I do not.

You are probably right. I had no lights and just assumed the switches were fed first as the lights in the other rooms are independent of the light/switch I'm trying to fix.

I will give that a shot and thank you very much for your help!

Don't forget the bonding (grounding) conductors. They are most important. If none are present then additional work is needed.
