Help with switch wiring

Hi,

I had to replace a 2 way switch in a junction box with 2 switches and 5 pairs of wires.
Some of the connectors came off when I pulled out the old switch and I can't figure out how to wire it back up. The breaker keeps blowing on any combinations I try.

This is currently how it looks. I'm not sure how to wire "B" and "Y" in the circuit.

Any ideas? Thanks!

If that's truly how things are wired, the only logical solution is Y goes to 1 and B goes to two. Even if you had the two reversed, I don't see how you'd be tripping the breaker though. You'd either have no working lights or lights that were constantly on regardless of switch position. I would maybe bypass the switches to figure out your connections first. Do you have a multi-meter? Are you certain all the whites were tied together originally? One could be wired as a hot.

Welcome to the forums.

I added cable numbers to your diagram.
You have a single pole switch too.

It looks like cable 1 goes to whatever the timer controls.
Your are showing cables 2 and 4 as connected together.
You are showing cables 3 and 5 as connected together.
You need to check the two pairs and find out which pair is currently hot.
The live/hot pair is common to both switches.

Yes I have a multi-meter to test. I'm positive all the whites were tied together before as the connection wasn't broken. I'll give a test with Y to 1 and B to 2 right now.

So testing with a voltmeter I'm not getting any voltage from pairs 1 or 2 connected to ground and nothing the proximity voltage detector as well? Could both pairs not be hot?

If you're tripping a breaker when wiring..... something must be hot. I'd check all five cables.

Crap number #1 or #2 weren't hot. Hmmm. I think I actually blew the fuse in the break box. I'm not getting any power to the receptacles or switches on that line now even after cycling the breaker over and over.

The other option would be both Y and B to #1. Regardless, you shouldn't be tripping the breaker unless you have a defective switch or light fixture or a short somewhere.
