I'm adding some new finished square footage to an already partially-finished basement. This includes cutting the link between two existing 3 way switches and wiring one new 3 way switch in with one of the existing switches to control 2 sets of lights from either end of the finished area
. The new and old switches are now wired together - the old switch is working great, but the new switch trips the breaker when flipped. Here's my chicken scratch attempt at how things are now connected. Any help is appreciated.
