Switch Keeps Tripping When Flipped On

I have a circuit that runs to 4 switches: 3 exterior lights and 1 foyer light. One of the exterior switches leads to 3 carriage lights. I previously had one of the Home Depot automatic switches in there but I decided to take it out and put back the original switch.

Unfortunately, that switch now trips the breaker every time. The other 3 switches all work just fine. So I'm guessing the breaker is fine.

There's been no nailing in the area that I think leads to the carriage lights. I am wondering if it is one of the carriage lights that is causing the problem and how I could pin this down.

Previously, that automatic switch was working fine but I did notice something odd, the lights would be on at a low level if it the switch was supposed to be off. The lights I used were LEDs candelabra style. I just tried one of those in another carriage light (on another circuit) and they tripped the breaker after a few seconds -- very odd. Took out all the LEDs thinking it could solve the problem. Nope, switch still trips breaker with regular incandescents. I tried different switches, even a 20 amp one.

I'm so confused...

It would help if you could remove the power to the circuit, pull the switches in the box and post pictures of the wiring. Hopefully it was a small mistake in placing a wire in the wrong place. Do you have a link to the "automatic" switch you removed? Did it require a neutral to operate? http://www.doityourself.com/forum/el...your-post.html

Remove the load wire from the switch and see if it trips. Also look to see if a hot is close to a ground in the box. Was this a switch loop that was rewired?
