You should have a three wire cable between the two three way switches. Do you see this? How many cables do you see inside the switch boxes?
The round junction box you show on the left side of the drawing, how many cables for sure go to this box?

Both switches have 3 wires and no ground. The round junction just connects 2 blacks 2 whites and 2 grounds. Almost like they ran out of wire and just adding on.

Wiring new lights in garage Question


OK, one more piece to the puzzle.
Now, look at the screws on the three way switches ignoring the ground screw. Is one screw a different color than the other two screws or is there some reference printed in the case calling one a common?

I replaced switch #1 with a new one ( thinking this maybe a problem) and yes one screw is a different color than the rest. Switch #2 has all the same color screws

Wiring new lights in garage Question


It's a start. We need to figure out how the lights are connected to the switches. What about the junction boxes where the fixture cables are connected. Tell us how all the wires are connected in them. We also need to which screw connection is the common. That screw will be a different colour than the other two, usually black.

In switch box #1 the black screw is on the red wire.
Switch box #2 has all the same color screws and don't see anything labeled common

In the junction box where there is 4 cables going into it. all 4 black wires connected together.. all 4 white are connected together and all 4 grounds are connected.

In your sketch of the circuit you show one cable going between switch one and switch two. Switch two has a red, black, and white wire so in the switch one box, find that cable and tell us where those same three wires are connected.

You're getting good at the sketches.
The switch one isn't wired correctly but let this sit for awhile.
Are you sure that each fixture only has one cable in the box? Something is wrong because we haven't found the power source for the light circuit.

So i went and turned off the breaker to that circuit and used my tester. The one wire that goes into the house from the 4 cable junction box, powers 2 more outlets and 2 more switches inside the house or the power is run inside the house first then out to the garage..

What if i pulled the cover off the fuse panel, I'd be able to follow that cable off that specific breaker and see where it goes??

Ok I followed the cable at the fuse panel. It runs into the house. I'm not sure if it goes to the outside light fixture or the outside light fixture switch. But other than that. I think I have everything mapped out right.

::EDIT:: It looks like fixture #1 is still missing power somewhere

Is the junction box and sw1 two different boxes? According to your drawing fixture #2 has no switch controlling it. Looks like sw2 has a second cable not shown on the room map. Can you figure where it goes? The bottom right black wire looks to be the common.

Junction box and sw1 are 2 different boxes. Yeah Fixture #2 just has one cable and runs to the junction box. But both switches turn on and off both fixtures. Switch 2 has only one cable that runs to switch 1
